Receptacles are specified by amperage and voltage (15A or 20A, 125V or 250V), by configuration (standard, GFCI, USB-integrated, tamper-resistant) and by mounting. GFCI protection is required in kitchens, bathrooms, garages and outdoors in most jurisdictions. Plates have to match the device count and the opening style, and a plate that does not sit flush is the most common cosmetic complaint after a renovation.
This group covers standard and decorator receptacles, GFCI and USB versions, and wall plates in one to four gang configurations.
