Why does the main breaker in some electric panels look like four breakers with a common toggle instead of the usual two?
Thursday, June 20, 2019
The GE line of main breakers is one we know of that does this, and only for their 150-amp and 200-amp 240-volt main breakers. Square D, Cutler Hammer, and Siemens also have similar breakers. It is essentially two breakers in parallel for each of the two 120-volt hot legs, and the only answer we could get from GE tech support as to why it’s like that is “that’s just the way GE designed it.” Which is good enough for us.
