I was tracing circuits and making panel schedules today and
found a 30 amp 3 phase twist lock receptacle, fed by 2 -3 pole 30 amp breaker . .yes,you read right two 3 pole breakers . . .3 # 10's from each breaker to the receptacle.
has anyone seen something like this b4?
 
Oddd...

Haven't seen that one yet but saw 4 #14/3s ran in parallel to one range receptacle being fed under a 50A 2pole :-?
Also- has anybody else seen a 60A 1pole breaker before? And what was it used for? This particular one was tied to a 12 gauge wire in a house :mad:

Well, that should be good for 60 amps, right? ;)

Maybe they needed a 60 amp circuit and made do with what they had on the truck.

So what's the problem. 30 amps travels on one set of #10's and 30 amps can travel on the other. The first set won't let more than 30 amps because it knows it will overheat thus sends the additional current to the second set. But how does the current know what set is the first set? :grin:

What struck me as I was thinking about this more, is that the people who installed this either-
A- lucked out with correct phases
or
B- actually knew what they were doing in a sick evil way.
