Was called by a Sams club in Virginia the other day with a question as to whether they had a emergency generator plug for their store. the management had stated that their records showed they had one but needed me to confirm. I went out there and looked around starting at of course the main service. There was no indication of a transfer switch and what I would expect is a large weatherproof cover/box that would allow for a three phase semi loaded generator to be plugged in for temporary service. Anyone have some input on this? Better yet, a picture of such a thing?
