The Arcon 13988 RV tri-adapter plug converts a 30 amp TT-30 outlet to a 50 amp RV style female connector in a compact block style design. A TT-30P male plug on one side and a 14-50R style receptacle on the other let a 50 amp RV cord connect directly to a 30 amp source for limited service.
This adapter is useful when you have a 50 amp RV but only 30 amp hookups are available, and you need a small, easy to store adapter without a dogbone cord.
Q: Does this adapter give my RV full 50 amp capacity?A: No. With a 30 amp source you must treat the coach as being on 30 amp service and manage loads accordingly.
Q: When is a block adapter better than a dogbone?A: Use a block adapter when you want the smallest footprint and the pedestal outlet and cord are well supported. Use a dogbone when you want more strain relief.
