What is the best way to insulate a positive contactor terminal with more than one wire connected? The rubber insulating boots that I have seen are made to be used with a single wire on the terminal.

I suggest you not worry about it. We had
some discussions about this waaayyy back when.
One builder suggested building a cover for the
contactor intended to shield 'dangerously
exposed terminals' from accidental contact/shorts.
Bad idea . . . these critters run warm NORMALLY
and are designed to perform in 'open to
the environment' conditions. Any enclosure
could emulate a tiny oven where the contactor
is deprived of expected air flows.

Consider this picture I took on the A36
production line at Beech. Talk about
spark-hazard-city! Yet, just like the
bus bars behind the breakers, these
are considered to be exceedingly unlikely
sources for sparks-in-the-dark . . . or
otherwise.

I don't know about "best," but self-amalgamating silicone tape makes a good insulator for pretty much any size or shape terminal. It's available on eBay for cheap, or under the trade name "Rescue Tape." If you're not familiar, it's a tape with no adhesive that sticks only to itself. Stretch it as you wrap it, and it sticks instantly and permanently.

Okay then! I'll forego the rubber boots.
