250A Disconnect switch wire binding screws
The 250A disconnect switch (standard and high SCCR)
installed for main power connection accommodates 4 AWG
– 350 kcmil wires on the "OFF" side. As shipped from the
factory, the wire binding screws only accommodate 3/0
AWG – 350 kcmil wires. If 4 AWG – 2/0 AWG field power
wiring is used, then the factory installed wire binding
screws must be replaced with those that are provided with
the kit installed near the disconnect switch (these screws
should have a blue top surface). See the kit for instructions
on changing the wire binding screws.
