use Alum plate instead of wires
use Alum plate instead of wires
(OP)
I have an application where I need to wire two contactor in series (redundant MCRs). They are in line with each other. The wiring connection is a tab with a 1/4-20 bolt/nut.
My assembler would like to use a bolt-on alum plate the same size and thickness of the contactor's alum connection in lue of wire with crimp lugs.
Anyone see an issue with this? Would it turn some heads in both the UL and CE circles?

This should be decided by engineering judgement and not ease of assembly.

Also, it is not at all probable that your contactor tabs are made from Al. More probably from tinned or plated Cu.

Use copper bars instead of Al. You can buy after-market plating materials if you so desire, although it may or may not be necessary. Contactor parts are tin plated mainly because the mfr. has no idea where the contactor may be used, but in many installations it isn't all that necessary.
