Electrical wiring in homes that display the MHMA/TCA seal conforms to the National Electrical Code (NEC). The NEC, sponsored by the National Fire Protection Association, outlines safe electrical practices for homes, businesses, and communities. The code was first written in 1897 and has been continually upgraded to make construction and installation methods in your home as safe as possible.
The NEC requires that 120-volt electric circuits consist of black- insulated wire for all hot lines, white wire for circuit neutral, and green-covered or bare-copper wire for the safety ground. In a 240- volt system, red-covered wire carries the other hot side (opposite white).
Some air conditioners and water heaters, most electric clothes dryers, self-cleaning ovens, and electric ranges operate on 240-volt circuits. Appliances requiring 240 volts utilize special large three- prong plugs. Your lighting system requires only 120-volt power.. Small appliances for 120-volt operation have two- or three-prong plugs, the latter being safest.
NEC and ANSI standards apply to other facets of the wiring in your mobile home. In homes wired with metal-sheath conduit, outlet boxes must also be of metal. Nonmetallic outlet boxes must be used only in systems using cable with nonmetallic sheath, such as plastic. If you must replace or add an outlet box, be sure it’s of the same material.
This tip can apply to all your electrical repairs. Duplicate original equipment in size, type, and material. Not only does this aid successful repair, it protects your safety.
