Questions & Answers

Will a TT-30 receptacle fit in this cover?

Asked by: Cashby
Hello, The cover is designed for receptacles with face diameters of 1.56" - 1.60". It is compatible with standard 20A and 30A locking receptacles. The device you're referencing looks to be a 30A straight blade device which is a larger face diameter than a locking device, and unfortunately will not work with our plate.
