US wiring
• The minimum recommended wire size is 6 AWG. (The
terminal block will accept cables up to 6 AWG size).
• The cable entry is via the 1¼ inch cable entry hole on the
bottom right hand edge of the back plate.
• Strip and connect the conductors from each circuit breaker
to an L1/L2 pair on the terminal block. Conductors from
each phase must be connected consistently to either L1 or
L2 as shown in the Fig. 6.
• Any insulation on the ground wires should be stripped back
about ¾ inch. The ground leads must be connected.
• Make sure the terminal block screws are tightened
securely. Loose connections can cause wires to overheat.
• Make sure that the ground wires are wrapped around the
terminal stud and into the saddle washer. The nut should be
tightened securely.
• Attach the front cover and tighten the retaining screws.
The WH36 requires three independent 220/240V AC circuits
protected by three separate and independent double pole
circuit breakers (as shown) rated at 60 amps each.
