someone used two single 15 amp breakers to do the work of a double 15
amp breaker. is this safe and/or legal?
doesnt matter much, as it is a GE panel and they seem to have a bad
rep. planning on replacing with a siemens that seem to be all the rage
If the circuit it supplies is a multi wire branch circuit that serves
only phase to ground loads and there are no yokes or straps on which
both ungrounded conductors are terminated then it is not only legal it
is best practice. If a handle tied or common trip breaker is used on
multi wire branch circuits a single fault will unnecessarily deenergize
both legs of the circuit. There is no good reason to have that
happening unless unqualified persons will service the buildings wiring.
"This alternating current stuff is just a fad. It is much too dangerous
According to Member, Takoma Park Volunteer Fire Department
I realize that this is legal in the US, but why is it best practise?
Here, we don't have any of the single yoke stuff. If it shares
a neutral, or feeds the same box (without dividers), the breakers
have to be gang-tripped, period. There are some exceptions which
I'll mention later.
I appreciate that in most cases it's "unnecessary" to kill both
circuits. But breakers aren't very smart, and I don't _want_ them
attempting such judgements ;-)
You mean, like the homeowner?
We have that clause in our code, but, the assumption is that unqualified
persons (eg: the home owner) _will_ service the building's wiring. So,
the exceptions to the "ganged breaker" rules require such things as
locked cabinets with only licensed electricians having the key.
You wanna do that with your house? ;-)
Which is why these exemptions are only applicable in commercial or

It\'s not just anyone who gets a Starship Cruiser class named after them.
Don't believe they have to be 'tied' together, unless each breaker
feeds a same device.
What is this being used for? Multibranch circuit of receptacles?

P.S. Only follow codes, not NG posts. :p
to all posters.....
I have two 120v 15a breakers that are doing the job of a 240v 15a
the reason I found this out is that I wanted to wire in an additional
240v breaker for a welder (completely unrelated)...anyway while looking
in the box, i see bad things, like a loose ground wire wrapped around
another ground wire that is screwed into the neutral bar ( i fixed
that!) and other stuff.
(btw, couldn't find the proper breaker for the GE box, odd size, etc,
ended up sharing the range breaker, the 2 will never be used at same
time, also plan on getting new box to fix all the other issues)
ok, ok, ok, I'll get back to the story. I noticed a couple of white
wires going to breakers (huh? oh 240V equipment) and found that the
240v line going to the well pump was actually not on a ganged breaker
(didnt know the term), but two discrete 120v 15a breakers.
even more fun, this 240v line goes to a fusebox that is used(i guess)
as a disconnect switch for the well pump.
I do see an issue where part of the pump could short out, kick off one
breaker, and a repairman goes to fix it and gets 120V where there
should be none, but as i said, i am going to replace the box with a
bigger one to help organize the wiring and get everything up to my
but is it legal as is?
odder and odder it gets.....
