PowerBreaker Safety RCD adaptor

Available from Homebase, the Powerbreaker comes with a three-year warranty. Uniquely out of the RCDs tested, it has only one button for test and reset functions. This is located out of the way on top of the adaptor, encouraging further investigation if the unit trips. The good news continues with a large status window (20mmx17mm), showing red or white depending on the state of use. Not cheap, but with the second best time, this was ourRecommended buy.
