I use these on a daily basis. I will most likely install one tomarrow. I have not had one fail yet and I have probably installed 10 boxes allready. IMO Leviton is not that great with their lower-end devices either. The receps that come in 10 packs from the orange box usually fail within a year. I would much rather install P&S, Bryant or best yet - Hubbell devices over just about anything you can get from the orange box but it comes down to - it is not my call.
I would rather beg for forgiveness then beg for permission.
FYI, Leviton stopped manufacturing in Canada some years ago. Canada never made GFCI's. The GFCI's were first made in the Brooklyn plant, then in the West Kingston, RI, plant, then they moved to Tijuana, Mexico. A plant in Singapore used to produce GFCI's for Leviton, don't know if they still do. Leviton (last I knew) had two plants in mainland China, initially making telcom stuff.
How to recognize Leviton devices under other brand names: look for coding on any packaging (box, instruction sheet, etc) in the following format:
LL-AAA-AAAAA-AAA, where L is always a letter, and A could be a letter or a number.
The GFCI's were first made in the Brooklyn plant, then in the West Kingston, RI, plant, then they moved to Tijuana, Mexico.
I always thought that they were made at the Hillsgrove plant in Warwick, RI. Interesting. Last I heard, they have all but stopped manufacturing at Hillsgrove, leaving only the distribution center in operation.
As for the Commercial Electric GFCI's, they did have striking similarities to the Leviton ones, however, I noticed that the plastic near the ground pin hole was very thin so I didn't bother buying any. Good deal, yes, but I am suspicious of stuff without a brand name on a special run from places like HD. I'll stick with the brand names.
