What are you running that makes you NEED a 300 Amp circuit breaker?

i have considered many packing packing containers with 2 unmarried breakers of inspite of length, tied which include a cord via the holes interior of both swap levers, (in order that as that they both throw mutually), that function basically positive. The quite ideal way is to have a double breaker of inspite of amperage is needed, (on your case, 20 amps), to do the pastime. If fee is prohibitive the position you stay, for the double 20 amp then basically purchase yet another unmarried 20 and set up it the position the only went undesirable. i'd, although, tie both levers which include a cord, in order that that you recognize those 2 bypass mutually. as long as they're correct aspect by making use of aspect, they're going to be one on each and each and every leg of the 220 line.

is this referring to a fuse? if so kicker makes 300amp ones
