hi lads

I need a pretty big (normal "non-reversing") three-pole contactor, and
the friggers are pricey. so used is OK. my finished product doesn't have
to pass code or ANY sort of elec'l inspection. I've noticed reversing
contactors sometimes sell for less than 'normal' three pole contactors
on ebay. I need to end up with something in the 'nema size 2' range.
maybe bigger.

I'm thinking I can buy a reversing contactor (or motor starter), remove
any neccessary 'crossbar' connectors and small wires, and end up with a
normal (non-reversing) contactor *plus* some spare contacts and screws,
etc. obviously, I'm not talking about the 'new-fangled' solid-state
contactors here (nor do I want one)

so, that a doable do?

Generally speaking, there would be no need to cut or grind anything.
The only difference between two separate contactors and a reversing
contactor is that the reversing ones are interlocked to prevent both
sides from being pulled in at the same time. If you only need one side,
you could just ignore the second set of poles and consider it a spare
standby contactor, ready to be swapped in with just a few minutes work.



if cutting or grinding (of the phenolic contactor body, or of steel, or
copper bars is involved, I can handle that "no big deal"

please, no 'dire safety warnings' or 'I'm an OSHA dishrag' type replies.
this is just a 'assuming the correct skillset, and the right tools, can
it be done?' type question; I'm not here looking for 'binding legal
opinions' or seeking safety advice

*thanks* guys :-)
