Our cities, towns, states and the entire country are crisis-crossed withpower lines that ³carry´ the electricity. As large generators spin, they produce electricitywith a voltage of about 25,000 volts. A volt is a measurement of electromotive force inelectricity. The electricity first goes to a transformer at the power plant that boosts thevoltage up to 400,000 volts. When electricity travels long distances it is better to have itat higher voltages "more efficiently at high voltages".

The group found that using the waste heat with optimal controls consistently delivered higher oil temperatures and significantly reduced warm-up times. This translated to fuel economy improvements of almost 4% compared to conventional thermal management strategies. The largest efficiency gains occur while heating oil from a cold start, and approximately half of the improvement comes from the powertrain and transmission sides.

"AFCI’s give great fire protection to homes with older wiring,” says Mike Holt, licensed electrician, electrical inspector, instructor, and founder of Mike Holt Enterprises, providers of educational resources to those in the electrical profession and related fields. Currently, the National Electric Code requires AFCI breakers for circuits providing power to bedrooms, living rooms, family rooms, and other common rooms in new construction. The cost for an AFCI breaker varies by manufacturer, but consumers can expect to pay around $30 to $35 apiece.

In 1897, the National Fire Protection Association established the National Electric Code (NEC). The National Fire Protection Association was a group of Insurance companies that were concerned about the potential danger inherent in faulty electrical wiring. They had cause for concern. Early wire was bare or covered with cloth. There was little understanding of the need for insulation.

If the box is metal, add a pigtail—a 6-inch length of the same type of ground wire—to the ground wire connection, then connect the loose end of the pigtail to the ground screw on the box. Join the white (neutral) wires together, then join the black (hot) wires together. If there are red (hot) wires, join them together. Confirm that all wires are secure by gently tugging on each wire.

Regular testing and evaluation of receptacles, switches, and breakers can prevent dangerous situations down the road. There are two electrical upgrades that should be installed to protect your home: ground fault circuit interrupters (GFCIs) and arc fault circuit interrupters (AFCIs). GFCIs protect against electrical shock caused by ground faults or leaking electrical current. These devices monitor the current in a circuit and interrupt or stop the flow of power to that circuit if a spike or loss of power is detected. In new construction, GFCI receptacles are required by code in bathrooms, kitchens, and garages, on outdoor outlets, and in crawl spaces or unfinished basements.

New appliances come with their own electrical challenges, which is why many people choose to pay for the installation. Yet, if you're a true DIY-er, you can install a dishwasher without problems. The dishwasher comes with two hook-up challenges: the wiring and the water and drain lines. That's why it's a good idea to choose a location near your sink. It will save you time and money. Why oh why do you have to buy a dryer cord separately? It's one of the great mysteries of home improvement, but it's a fact of life. Next time you need to install that new dryer, you'll be prepared after this tutorial.
