Query: USA quality

This item seems to be a quality device. Well-built. Functions as intended. Easy to install but if you have any concerns then you should call upon a qualified Electrician. The directions call for this to be installed near the panel but I however chose to install it near the furnace. Works just as good and I wired it into the junction box next to the furnace, no problem. I look to upgrade to a Reliance Pro/Tran multi-circuit manual transfer switch in the coming months.
