I am upgrading a panel located in the garage of a home. The panel is on a wall connected to the home.
Before I mount the panel on the plywood, do I need a sheet of 5/8 fire board behind the plywood?
That was a requirement many years ago...
On a rare occasion I still do it to space the panel out for cleaner offsets with conduit or spacing of large connectors.
Permit is required for all electrical work; and if you are not an EC (unless it is your own house) you can't do the work anyway.
