You could extend that to doing anything that would require a permit, without pulling a permit- if you get caught after the fact, it could end up hurting big.How does any authority know that you plan to, or even if you did, swap a breaker panel on your own? Does your local Lowes Depot require proof of license at point of purchase?
If I need to replace a breaker panel, I buy one and do it. Never even thought to call any inspector to ask for permission or inspection, any more than I’d think to ask them to come evaluate my wood splitting skills.
