I'm looking to install a whole house surge protector in my 150 amp panel. I remember an electrician telling me that the panel is at max capacity despite there being a few open slots.
Slots 2 and 4 (hopefully "slots" is the right term for it) are currently open, which I believe would be the right location to install the whole house surge protector. My question is, can I even add the surge protector if the panel is already maxed out? I have no idea how this all works.
Any advice will be greatly appreciated!
