MULTIPLE HEATERS ON ONE CIRCUIT BREAKER
(240 OR 208 VOLTS ONLY)
1.
Route the electrical supply wire from the circuit breaker to heater #1. Remove two knockouts and
attach two sets of electrical supply wire with two cable clamp connectors (not included) leaving a
minimum of 6 inches wire lead—one set from the circuit breaker, the other set to heater #2 (See
Figure 7).
2. The two supply ground wires in the wall can of heater #1 need to make a 3-wire connection with the
grounding screw. Attach a short copper ground wire to the grounding screw in the wall can. Connect
this wire and the two supply ground wires with a wire connector (not included) (See Figure 7).
3. For heater #1, connect each heater wire with one of the supply wires going to the circuit breaker,
and one of the supply wires going to heater #2. Each of the wires from heater #1 must have a 3-wire
connection. For heater #2, make the connections in the wall can as shown below.
More than one heater can be wired in parallel on the same circuit breaker (be sure to check national
and local codes for safety requirements). Additional electrical supply wire and cable clamp connectors
are required. The heaters must be in the same room.
Maximum amperage you can put on one circuit breaker is limited to 80% of the circuit breaker capacity.

2. Insert the bottom edge of the heater assembly into the D-shaped tabs at the bottom of the wall can.
For heaters mounted with the element at left, insert the right edge of the heater assembly into the half
round slots (D-shaped tabs) on the right side of the wall can
3. Push all wires back into the bottom (or right side) of the wall can. Make sure connections are tight
and none of the wires are caught between the motor and the wall can, or pinched between the side of
the heater and the wall can.
4. Attach the heater assembly at top (or left side) of the wall can with screw provided.
