Using a hole punch, cut a hole the proper
size for conduit connection; large enough
for the wire size for each heater. The
connectors need to be rated NEMA4/4X
to ensure proper sealing of the enclosure.
A
Open enclosure door.
C
Run wires through the appropriate size
conduit.
D
Connect wires to the system terminal
block or fused disconnect inside the
enclosure.
E
Connect the ground wire to the stud
provided with the “Ground” label beneath it.
NOTICE! Any option that requires field wiring
must be done with 600V cable per the
schematic that was shipped with the
heater.
NOTICE! Use a 4-core cable or multi-stranded
machine tool wire from an approved
isolating 3-pole switch or circuit
breaker.
NOTICE! Make sure the electrical cable is the
correct size to carry 100% of the full
load current. See table for proper
wire sizes.
WARNING All Keltech heaters must be fused in accordance with National Electric Code (NEC) for the
full load amperage listed on the nameplate rating for each heater.
