Which numbers identify inputs and outputs in circuit breaker

Home Improvement Asked by Rubus on February 19, 2021

Numbering of circuit breaker

I have always though that the numbering on the circuit breaker is in as such that the input wire (supply line) is 1 (3,5,7) and the output wire is 2 (4,6,8). However today I discovered that in my panel the input wire is 2, and the output wire is 1. Is this correct? And does it matter?

One Answer

It can go either way. often the feed to a panel goes "backwards" through the main breaker (compared to the other breakers).
