Get a PAT (Portable Appliance Tester) and tag each appliance with your test results and you can have your Co. Identity on the tag too!, especially for re-test purposes, people that work where these bits of equipment are used would read your name on there.
We do HEAPS of this sort of business, BELIEVE ME!.
