Looks like that takes up 2 slots, any idea how many breaker slots are in an Easytouch 8?
The hepd80 here, which is externally mounted, does recommend connecting to its own 20-amp circuit, which is what I did, but can be connected to existing circuit, as it draws very little current. This unit is rated for 80KA versus the 27KA of the other, and provides line-line, line-ground, line-neutral, and neutral-ground protection.
