Electrical Wiring Information

Refer to the Electrical Rating Charts in the SPECIFICaTIONS
section for unit specific information.
WARNING
ELECTRIC SHOCK HAzARD: For hardwired units, all
electrical connections must be in accordance with local
electrical codes and any other applicable codes. Connections
should be made by a qualified, licensed electrician.
CAUTION
Strip heaters equipped with incandescent lights that
require a circuit breaker larger than 20 amps for the heat
element must have a separate circuit breaker for the
incandescent lights that is 20 amps or less.
NOTE: If the unit being installed is not shown or listed in this
manual, refer to the wiring diagram supplied with the
unit and the installation information on the unit for
further instructions.
Power Supply
Install supply wire and connectors suitable for at least 194°F
(90°C).
• Use a minimum of No. 14 aWG copper wire for individual
circuits up to 15 amps.
• Use a minimum of No. 12 aWG copper wire for individual
circuits 15 to 20 amps.
• Use a minimum of No. 10 aWG copper wire for individual
circuits 20 to 25 amps.
• Use a minimum of No. 8 aWG copper wire for individual
circuits 25 to 30 amps.
NOTE: Refer to the wiring diagram supplied with the unit and
specifications label attached to the unit for specific
electrical information.

Remote Control Enclosures
Hatco remote control enclosures include switches, wire leads,
and/or indicator lights and are ready for installation.
The RmB Series require one remote control enclosure per strip
heater. The RmB2 Series allows multiple strip heaters to be
connected to one remote control enclosure.
NOTE: Remote control enclosures are available in several
configurations depending on the model. All enclosures
are built in accordance with UL standards to
accommodate switches, indicator lights, and wiring.
See the OPTIONS aND aCCESSORIES section in this
manual for more information.
IMPORTANT NOTE:
Remote mounted enclosures and control switches must be
installed in a cool, dry location as far away from any heat zone
as possible. Do not mount enclosures or switches directly on,
under, or above unit. Do not mount enclosures or switches in
direct contact with any heated surface or near any steam
generating equipment.
NOTE: When two or more units are mounted where the heat
from one housing tends to raise the temperature of
another, the control switches should be installed in a
remote control enclosure. Units in a multiple installation
should use remote mounted control switches.
To prevent premature failure of components due to
excessive heat, remote mounted control switches must be
installed outside the strip heater heat zone.
