I'm finishing my attic and need to wire it (about 8 outlets and 14 LED recessed lights; also a half bath with GFCI outlet, fan, vanity light). I have gotten four electrician bids. Two said my existing 150 amp panel (installed in 1975) does not meet code and I need a heavy up to 200 amps. The third company said I just need a subpanel for the attic lights. The last one said my existing panel is fine.
I have attached photos of my panel. We will be adding two circuits (20 amp an 15 amp). Is it possible to tell from looking 1) whether it has the capacity for these breakers and 2) whether the panel itself meets code? The companies that said it needs to replaced told me that there is something wrong with the way the breakers are arranged.
