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 90°C
(194°F).
• 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

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: See the OPTIONS AND ACCESSORIES section in this
manual for more information.
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 control
enclosures.
To prevent premature failure of components due to
excessive heat, Remote Control Enclosures must be
installed outside the strip heater heat zone.
