Remodeling a 1970’s era condo. The current dryer receptacle has a NEMA 10-30R on a 30 amp breaker. While we are going to be using gas instead of a 240v dryer, I decided to pull the plate and make sure the lugs were snug and tight.
When I pulled the plate, I found the ground and neutral were both under the same lug which I “think” is supposed to only be for the neutral white wire (see photo).
If I were leaving the 10-30R receptacle, is this proper or should I pull the ground off the lug and just cap it leaving only the white neutral and both hot phases? I understand that ground and neutral are bonded at the main service panel and have learned bonding anywhere else is wrong in residential wiring.
