“Definition: When I say ‘double-tap’, I’m actually not using the correct terminology; this is just what a lot of home inspectors say when two conductors are connected under one screw or terminal inside a panelboard. There is no official term for this, so double-tap works for me. Sometimes this refers to two conductors at one circuit breaker, other times it refers to two conductors connected under one screw at the neutral bar. Today I’ll discuss two conductors connected to a single circuit breaker.
Why it’s a problem: If the circuit breaker isn’t designed to hold two conductors, the conductors could come loose at some point in the future, even if they feel very tight today. Loose conductors can lead to overheating, arcing, and possibly a fire.”
