I'm studying residential services and in the book i have they are talking about how a GFCI work's. I know the concept but what im not understanding is current imbalances and neutrals, which i know the neutral carries the unbalanced load but i thought that between two phases it would always be the a number divisible by two 240/120 and so on.
In the GFCI chapter they say "If the current in the neutral wire becomes less than load in the hot wire, then a ground fault exists" but earlier in one of the other chapters they are quoted as saying "In a single phase feeder circuit with one phase carrying 50A and the other carrying 40A the neutral conductor would carry 10A.
