I know SD makes breakers that can be doubled tapped but can their tandem breakers be doubled taped also?
Didn’t think so,Thanks
Also many Square D panels do not allow tandems, some do, at specific locations on the bus bar.
I don’t remember where I got this but it appears connected like a possible 240 V breaker.
Anyone know for sure?
That’s a bolt-on breaker where the screws attach to the bus. Only house you’ll ever see that in is one owned by a sparky.
Can it be use as 240 volts?
Yes, it’s pretty much a standard 2-pole circuit breaker but instead of using snap type clips to attach to the bus it uses screws (bolts) threaded into holes in the bus, hence the name bolt-on.
Thanks for the education, Robert! I appreciate it.
