All 20-amp receptacles are Specification Grade.
Not so sure about that. Leviton has a 20 amp T-slot in residential grade.
20 amp T-slot residential grade recept.Leviton also has this one in 15 amp residential grade.
FWIW, I have a single 20 amp T-slot SCD RV receptacle I took out of a previous TT. I don't think they have a grade designation on RV wiring devices?
Agree on going to a better grade receptacle like spec. grade for plugging in something like an RV. If you want even better retention force, try a hospital grade one... ;) Larger gauge wire, at least #12 is a good idea too. I ran #8 (50 amp) to the 30A recept. in our carport.
