Essential Elements Ordering Overview
20/208-volt line-cord connected units — order line cord kit.
20/208-volt sub-base connected units — order sub-base
(includes power connection kit) and junction box for chassis.
265-volt units — order sub-base and power connection
kit separately.
Electrical Wiring Information –
2900/900/5800 Series
All Zonelines are single-phase 60 hertz units.
For all installations, the feeder, sub-feeder, branch circuit and
electrical protective devices and selection must conform to
the National Electrical Code and to local codes.
Maximum connected load in amperes, including demands
for the electric heater and the fan motor, are shown on page
44. Branch circuit ampacity and electrical protective device
sizing are shown on page 42 for 20/208-volt units and on
this page for 265-volt units.
More than one unit per branch circuit is not recommended.
When in doubt, consult the National Electrical Code. All
wiring, including installation of receptacle, must conform
to local electrical regulations and codes.
Replacement of Existing Chassis
230/208-Volt and 265-Volt Units
There have been changes to NEC and improvements and
modifications to the Zoneline chassis and sub-bases since
the unit was first introduced. Some of these changes require
alterations to be made when replacing an older unit with a
new chassis.
Line-Cord Connected Units
The plug configuration of new line cord connected units
complies with the current NEC standards. Older installations
may have wall receptacles that conformed to NEC standards
at the time the building was constructed and may not match
the configuration of the plug on the new line cord. The
recommended solution is to change the wall receptacle to
conform to current standard plug configuration. See chart
on this page for current receptacle configuration.
