WIRING REQUIREMENTS for some common appliances are explained in this section. Appliances are connected to the power supply either by a cord and plug or by permanent wiring. Cord- and plug-connected appliances include those that are readily portable, such as toasters and vacuum cleaners. Some large appliances are permanently connected, and others come equipped with a cord and plug to facilitate servicing. Kitchen ranges, clothes dryers, and similar appliances are located on individual circuits. Some appliances are fixed—that is, fastened in place through plumbing connections or other installation conditions; examples are water heaters, oil burner motors, and central air conditioners. When you are in the market for a new major electrical appliance, consider the more energy-efficient models being offered. The initial cost may be higher than for a conventional appliance, but the savings in power used over the life of the appliance will more than make up for the higher price and will help to conserve energy. To encourage the use of more efficient appliances, some power suppliers have incentive programs such as a cash payment for junking an old refrigerator, or a rebate for an approved appliance purchase. top of page |
