disconnectorbreakerformaintenanceandsafety.
Manyswitchesandcircuitbreakershavelimitations
regardingmorethanonewireinaconnector.Breaker
manufacturerscanprovideinformationonthelimitations
oftheiravailableterminals.Whereadditionalwires
areprohibitedunderthesameterminal,manytimes
installinganewcircuitbreakerisconvenient.Typical
sizesare15,20and30amps.
6. Foroptimaldeviceperformance,useshortestwire
lengthofwireaspossible.Cutofftheexcesswire
