| Subject: | Multiple wires/ring terminals on the contactor? |
I've got three separate wires coming in to a terminal on a contactor. A 2AWG,
a 10AWG and an 18AWG. Currently each wire has it's own ring terminal.
This makes for a messy terminal with wires sticking out at all different angles
and makes it difficult to put a boot over the terminal.
I thought about combining the 10 and 18 gauge wire into a single ring terminal
which would clean things up a bit.
Then there's the challenge of getting all that wire to fit in the boot.
Just wondering how others have dealt with this scenario.

I believe on my contactor the stud was long enough that I could put
washers between the ring terminals so that they didn't interfere with
each other and then could be lined up in a neat and proper looking stack.
There are specific guidelines on using washers and ring terminals on
studs and such in the standards manual as I recall.

Don,
Can you move the #10 & #18 wire to the connector at the other end of the #2? Electrically
the same but that way the #2 is alone and can be booted.

| Subject: | Saggy bus voltage on Cessna 182 |
- Paul Millner kindly pointed me to the Cessna service kit to replace
the 60 amp CB, which involves shortening the bus bar so the replacement
breaker will fit. I think the approved breaker is $400 or thereabouts,
so if it does need replacing, does anyone know a PMA alternative?
Nowadays, we consider breakers standard electrical parts, and under the
advisory circular guidance, they don't require special approvals. I
understand Transport Canada may not have gotten to that point yet. That
said, Aircraft Spruce (even the Canadian flavour of same) have several
attractive offerings... You don't have to buy your wire and PIDG
terminals from Cessna with PMA do you?
BTW, at least one of the service bulletins is: SE76-15-Replacement of
Alternator Circuit Breakers (S1596-60L)

As a partial solution, you could turn one of the terminals upside down on the stud
so that it doesn't interfere with the one immediately above it.

That's what I'm doing now. But it doesn't help with that third terminal.
And running the wires to the other end of the 2AWG won't help as that end is pretty
heavily populated as well.

I can't see any downside to putting both in one connector, except the
ability to isolate each feed for troubleshooting purposes.
I do know that I've spent literally years on my project trying to go
from good enough to perfect.....

Hi Don and all,
That could work. Even better, with an *uninsulated* ring terminal for
those two wires, and stacking the terminals back to back you might be
able to keep everything in line

We just... put a larger boot ;-)
FWIW

I had another idea. Fabricate a copper, brass or aluminum tab similar to th
e attached image, allowing two side-by-side wires to head off in the same di
rection. One hole goes over the stud you're attaching to, along with the he
avy wire's lug. The two lighter wires' lugs go back-to-back, bolted to the o
ther hole. Size the tab for your hardware and available space. Use star wa
shers keep things from moving around.
