Question:
Hello,
Can I install a breaker panel with the main breaker at the bottom rather at the top?

Answer:
Hello Daniel,
Thanks for the question. Check the installation instructions that came with the panelboard. Often there is an option to install the main breaker at the top or bottom. See Section 110.3(B). Another rule to keep in mind is Section 240.81 which addresses orientation of the breaker and the up position, being the on position, unless the breaker is installed horizontally rather than vertically.
