Appendix I: Testing an Electrical Outlet
An outlet tester is the preferred method of checking an electrical outlet, although a voltme-
ter can also be used.
BACKGROUND INFORMATION ABOUT AC WIRING
Equipment running at 115VAC must have one hot wire and one neutral wire. Additionally, a
separate ground wire runs to non-current carrying parts of most loads.
THE WIRES IN AN AC OUTLET (115VAC)
*The service equipment is defined as "the equipment used to disconnect the entire building
and overcurrent device to protect the entire installation, but not the branch circuits individu-
ally."
At the service equipment, a single ground wire connects both the neutral and ground to
earth. The NEC calls this wire the "ground electrode conductor."

DESCRIPTION
FUNCTION
LINE
Usually black. Cannot be white
or green.
Carries the live voltage and current to
the equipment.
NEUTRAL
White or natural gray.
Grounded at the service equipment*
only. Serves as the return for 115 volts.
GROUND
Bare, green, or green with yel-
low stripes. May be metal armor
or metal conduit.
Grounded at the service equipment*
and every metal box or cabinet. Runs to
non-current, carrying parts of most
loads.
