I see enclousures with a single circuit breaker mounted in them and the handle operates left to right instead of up and down. There are no markings in the panel to indicate line and load. If the contractor installs the load conductors on the top side of the breaker and the line conductors on the bottom of the circuit breaker is this a violation? Manufacturer is silent on this matter. I asked the contractor to use a magic marker to label line and load and he agreed.
