PREMISES WIRING
The POWER-ARC 5500 three-wire, grounded neutral
generator allows it to be connected to premises
wiring. However, the wiring procedure needed to
meet the National Electrical Code (NEC) regulations
as well as city ordinances and can be confusing. The
connections could vary from a "commonly grounded"
to a "separately derived" system depending on
whether you want the unit to be "hard wired" or tem-
porary to the premises.
