Punch holes in the terminal block covers for the input, input bypass
(dual input feed only), and output conduit using a Greenlee
or similar device. The holes accommodate up to 2I IMC conduit.
Pull the input, input bypass (dual input feed only), and output wires
through separate conduit, leaving approximately 15 cm (6") of
exposed wire. Attach a flexible metal fitting to the end of each
conduit.
Insert each conduit through a wiring access entry and attach the
conduit fitting to the panel. Strip 1.5 cm (0.5I) of insulation from the
end of each incoming wire.
Connect the input and ground wires to the input terminal block
according to Figure 32 and Table 1.
