Electrical wiring is the most complex system in a house and is also the most dangerous when it malfunctions. Improperly installed residential wiring results in hundreds of injuries and deaths every year and many millions of dollars in property damage. Most any type of project that involves electricity should be done by a licensed electrician. Seasoned do-it-yourselfers may have the ability to do some projects if they are very familiar with wiring issues, potential errors, and current code requirements. It's wise for homeowners to understand the basics of home wiring even when an electrician is doing the work to have the ability of recognizing mistakes should they occur.
The many and varied materials needed for house wiring depend on a number of factors including the intended use and power demand, the building or project size, environmental conditions, and potential needs for future alterations. Knowing what questions to ask before beginning an installation will save a lot of time and make the installation proceed much more efficiently whether you are a professional or do-it-yourself homeowner. Though many licensed electricians work from memory, a home wiring guide can help organize the process and document answers for the electrician and the customers.
It is essential to have a complete understanding of safety codes and regulations in your area. These safety regulations in the National Electrical Code (NEC) are modified and published every three years by the U.S. National Fire Protection Agency (NFPA) and are included in local building codes. This is another area where a thorough checklist can be very helpful. The checklist can help to assure that everything has been done properly and with complete adherence to code requirements.
A home wiring guide is a very useful tool for both professionals and homeowners. Developed by a master electrician and licensed electrical contractor, it helps to organize and document any project of any size. It lists useful questions to ask and includes installation tips and preferences. It also contains current code references that correspond to many installation areas such as required circuits, grounding, loads, lighting, receptacles, and more. Do-it-yourself homeowners find a guide to be a good house wiring how to manual.
A very inexpensive home wiring guide can help save time and money and make any wiring installation go smoother without having to rely on memory. The documentation of the installation is a professional added value to the customer as well that can increase valuable referrals and repeat business.
The most popular ways for amateur radio enthusiasts, otherwise known as ham operators, to enjoy their pastime involve contacting people over their radio sets. This hobby is virtually unlimited as radio hobbyists reach people from different countries all around the globe. They contact people from other cultures, learning about different ways that people live.
Sometimes, there are contests for radio hobbyists where the ham operators contact as many people as they can in a given amount of time. In this case, only basic information is shared. The first things the radio hobbyist will find out are the other's location and station. The zone, region, and particular place are important too. The radio operator gets this information, signs off, and moves on to another contact.
DX-ing is a way of using the radio to contact as many Distant Stations from as many parts of the world as you can. DX-ing QSO means that you are having conversations with people in these far-flung places.
DX-peditions are another way radio hobbyists use their talents. They get together and organize group efforts to contact stations that are remote or special in some other way. The region itself may be far removed from civilization. Sometimes there is travel involved, as ham operators try to reposition themselves to reach these remote stations better. Radio scanners are also used, as they can search for a strong signal.
Another part of the amateur radio pastime is acquiring QSL cards. QSL is a set of three-letter codes. The codes were set up for use with commercial radiotelegraph systems. They were then adopted by amateur radio buffs who continue to use them to this day, even though they are no longer considered essential for amateur radio.
A QSL card can be used as a proof of contact card. This means that whenever radio hobbyists contact other operators through DX-ing and DX-peditions, they can show that they have actually contacted that station. Each station that makes contact will send a QSL card by mail. This proves that contact was made.
These cards can stack up to recognition because they show how good the operator is at contacting other stations. If you want to get more awards and recognition, one way is to make contact with the most remote regions where there are few operators.
Radio hobbyists can also enjoy their pastime by banding together with others who have the same interests. Hamfests are held frequently where the family and friends of ham operators have social events to share their experiences and simply have fun. There is also room at these events for sales and exchanges of equipment.
It may be possible for some people to meet familiar ham operators at these events. In other words, they may have talked to them for years, but never before had the chance to speak face to face. It is also a good time for radio hobbyists to do some networking with operators that are new to them. Besides all this, plenty of good ham radio discussions will take place at such a meeting. It is a good time to talk about all the special aspects of the amateur radio hobby and what makes it so special.
If it seems your winter heating bills are increasing for no apparent reason, the problem may not be with the appliances but with the home itself. Even if the electric baseboard heaters are working correctly, almost one third of the heat they produce can escape through walls, floors and ceilings. Other places the air can escape includes ducts, fireplaces, plumbing fixtures and around the windows and doors. By ensuring the home is properly insulated and sealed, the occupant can help to improve the efficiency of electric heaters.
Occupants can also save energy by ensuring the thermostat of their electric baseboard heaters are set properly. At night or when planning to be away from the home, the thermostat temperature should be lowered. However, one should not turn off the heater completely, as it must work twice as hard and use more energy in the morning. When on vacation, set the heater to automatic and leave it at a reasonable setting, usually no lower than 60.
When you want to save money and reduce waste, it can help to ensure that the heaters are clean and that dust is removed. Anything that blocks the vents or exhaust can cause the heater to use additional energy. If buying a new unit, it should be Energy Star compliant. Owners may want to consider units that offer an anti-freeze function that will turn on the heat if the room temperatures drop to the point that pipes could freeze.
Some baseboard heaters are more energy efficient than others. For example the Fahrenheat PHH15002 is an oil filled baseboard heater that works well in rooms up to ten by fifteen feet. It offers several safety features and is ideal for use in offices, bedrooms or even small living rooms. These units offer two heating levels and a built I thermostat. It is easily installed and requires very little floor space.
For a larger area that must be warmed, the Marley PLF504 offers a hydronic baseboard unit. This model is only 28 inches long and easily blends with most furnishings. It can be mounted on the wall high enough that the occupants can easily operate a vacuum underneath the unit. It uses proprietary technology to provide energy efficient heating for a room using a freeze proof liquid to disperse the heat.
Heating a room when it is empty usually makes no sense. Dayton offers the UG01, a portable unit that can be transported with the occupants of a home to the room being occupied. This model offers cost effective heating in a stylish and compact unit that is made to blend with nearly any decor. It offers many safety features, such as a tip proof mechanism and auto shutoff.
When choosing energy efficient heating systems for one's home, make sure you know the available power for operating the heater and the square footage to be warmed. To keep the home comfortable in the winter, select a system offering long term benefits, including electric baseboard heaters for a comfortable house.
The appeals of wireless network installation are numerous. The first, of course, is a limit to the number of wires running through a home or office. A wireless network also allows for a very simple installation, since your knowledge of wiring and electrical work can be minimal, but still be adequate for installing a wireless network.
Additionally, the wireless configuration allows you to have a great deal of flexibility in how you locate equipment around the home or office.
In order to set up a wireless network that is internet ready, you will need only two primary components.
The first is wireless LAN (or Local Area Network) cards. It's important that each PC on the network have its own wireless card.
They need to be inserted into an unused PCI slot located inside of a PC. The antenna portion of the card should be at the back of the PC with the antenna extending up.
Installing the LAN card is not a complicated operation, and can be accomplished by a novice in computer installation. Simply open the computer case carefully and find the slot where the LAN card fits. There is likely only one available, but any computer that does not have a built in wireless system will have a LAN slot.
Ground yourself by touching something metal or plastic to dispel static, then screw the card into the slot with the screws provided. Make the electrical connections, replace the PC covers, then start up the computer. You'll need to intall drivers specifically for that LAN card. Repeat for each computer that will be on the network.
The second component of a basic wireless network is the wireless router. These routers allow you to share a single internet connection between numerous computers. Depending on the router's specifications, they can accommodate between four and sixteen computers on a single wireless router.
If you have internet from your cable provider, they may have supplied a cable modem, but those are rarely wireless. You'll need to plug a wireless router into the modem, then route your PCs through it. If you have a DSL or ADSL connection, purchase a DSL modem.
You'll then configure your network. Log onto your router/modem through your PC. Read the owner's manual for the router for specific directions. You'll want to direct it to automatically assign IP addresses to any PC attached to it. It's recommended that you stick to basic network configurations and use the 192.168.01 as the first IP address and the 0.9 as the ending address, which gives you the potential for eight additional devices to be installed, if you like.
You want your router to be the primary gateway and also the primary DNS, so both of these boxes should be set to the router IP (188.8.131.52). Other boxes should be blank or contain default indicators.
The next step is to go to the Network Connections screen in a PC start menu, right click on wireless network and go through properties to indicate that you want the router to obtain an IP address automatically.
Is there anything more frustrating to a large family than having a washer or dryer break down? Heaps of clothing pile up or have to be lugged to Laundromat until a repairman finally shows up. The cost of appliance repair is always shocking, and sometimes the washer or dryer can't be fixed and has to be replaced altogether.
Although it's hard when an appliance quits working, it's downright scary when faulty wiring or some other defect causes overt danger to a family or home. It's important to know which appliances are the most likely to cause trouble, and do our best to prevent the ravages of electrical fires.
-- Air conditioners that are in continual use in dusty locations are definitely at risk because tracking faults can result from the settling of particles on electrical components. Air conditioners need to be dusted regularly to avoid such mishaps.
-- Dryers have an element that usually runs around the rear of the drying drum. Paper, lint, or any other combustible material that comes into contact with this element may ignite and cause an extremely dangerous situation. Make sure you keep the floor area around and behind the appliance clear of debris and clean the lint trap each and every time the dryer is used.
-- Hot water heaters, especially those of a considerable age, are liable to corrode in certain places. Water may leak through the resulting fissures, and if this moisture comes in contact with any of the appliance's electrical components, it may result in a fire. Have your hot water heater checked by a professional, and if it is old, it will need to be replaced.
-- Dishwashers have the same problem as all electrical appliances that deal with water: if moisture comes into contact with the electrical conductors at the top of the door due to leakage, a problem may occur. The heating unit at the bottom of the appliance operates at extremely high temperatures during the drying cycle, causing the most common reason for dishwasher fires. Keep plastic materials, and definitely anything paper, out of this appliance.
-- Refrigerators are another type of kitchen appliance susceptible to electrical fire due to water leakage. Check the drain tube from the freezer regularly to make sure it's not blocked up. Blockage during an ice-making cycle will cause water to overflow, possibly coming into contact with electrical circuitry.
Electrical fires can be prevented. The best overall advice is to never take the smooth operation of your appliances for granted: keep them clean, free from debris, and when appropriate, have regular professional maintenance done.
Bringing power into a building from the electrical lines that run from the street a single phase converter controls the flow of energy inside the building. Where an office might be set up with a series of computers that are backed up with emergency batteries and have surge protection the single phase system may not be sufficient to handle the load that the energy consumption requires. inide an industrial shop that is using a number of different machines to fabricate various products a 3 phase converter can make the difference between straining the electrical use and allowing each station in the manufacturing shop to be operating at full power throughout the day.
The installation of a rotary 3 phase converter allows drill presses, saws and other pieces of equipment to be run without adding to the energy costs or the electricity that is being pulled from the power grid. Adding to the energy efficiency of a business that is relying on the constant drain of the utility the converter is connected to the breakers that bring in power to the building and are loaded to increase the output of electricity without adding to the use of energy. The lower cost and higher output allow industrial manufactures to make the most of their utility consumption.
Hooked up to woodworking and steel machining equipment the converters are able to provide all the electrical power that heavy duty machines need to operate in a non-stop environment. Running air compressors, hoists and lifts and air conditioning or heating systems much more efficiently the addition of a 3 phase converter is able to boost the production of many manufactured goods without altering the amount of energy that is consumed by the building. In offices where server farms are required to manage the data flow that is coming into the system the converters can be added to the electrical equipment to make them more efficient in their use of electricity.
Available in three sizes that can manage different loads and deliver the same level of energy consumption to commercial and industrial complexes, the full capability of the 3 phase converter can be determined with an inspection of the property and the electrical usage needs of the business that is looking for a way to cut their utility bills down to size. Offering an alternative to paying for the rising cost of electricity that seems to increase each year the converters are the best way for a business to manage all of their energy consumption needs without adding to their utility bills.
