Mechanical stresses of 8 gauge copper may be more than the recepticle is capable of withstanding during installation. Please verify with Wattgate whether the recepticle screw mounts and the recepticle body can safely support 8 gauge. If they ok it, then I would use a deep double size wall box with a plaster ring. The larger box will allow for more gradual and safer bends of such large diameter wire.

I'd like to run a stranded copper 8 gauge dedicated power line in order to better power my Plinius SA-250 Mk 4 power amp. Does anyone know if this or any other wall receptacle can accomodate such a heavy gauge wire? And in your opinion is 8 gauge wire vs. 10 or 12 gauge overkill? I would appreciate any thoughts on this issue.
