equipment, design the system layout taking into consideration personnel
safety, operational function, convenience, and power cable length. In general, for 115 V ac systems the
total cable length should not exceed one mile (1.6 kilometer), but the length of cable between the stations
is not a critical factor.
A separate power feed is recommended to each station located in hazardous areas. With a separate feed,
individual stations can be de-energized for service or maintenance without affecting the power supply and
operation of the other stations in the hazardous area.
