Makes me wonder how many dual breakers I have taken the handle tie off
and used as singles in the past. It has been several, and none with no
internal connections that I could find or notice, with the exception
of longer rivets holding them together.
This is fairly easy to test for.
Remove the pin, reset the breaker handles and then basically apply a
battery across the breaker
terminals. If it is internally connected, both handles will flip
together even without
the pins tying them together for switching.
If you are afraid of sparks and arcs, use a 12V battery.
Use real wire. No rat shack clip leads !

Granted it has been a while since I have done that.

The Code requires parallel breakers to be designed for this
application (internally ganged).
Just using a handle tie does not allow you to use the poles in parallel.

Our 100 amp din rail is essentially 2 breakers in parallel. So in
theory the 2 60 amp breakers "Could" work but. My concern would be
that they may not be tripped at the same time where they are not
internally ganged. I can't say "Go Ahead" but.

We are installing the system today and I only have 60amp in stock.
Customer lives in CA and is leaving today after the installation.

Hello Wrenches,
I am installing a Classic 150 controller in an RV with
potential 95 amps output at 12 volts. The customer has a
Midnite DIN box and wants me to use it for the controller
output. I am out of 150VDC breakers but I have two 60 amp
breakers. Is it safe and reliable to use the 2 breakers in
parallel for this purpose? I can pin the two handles together.
There will be other circuit protection at the battery.
Thank you,
Larry Crutcher
