Has anyone had the following problem ? Testing a rewire we did last week, CU is a new type Steeple ( Made for Denmans by Crabtree) with a mixture of RCBOs at one end and a traditional RCD at the other , guarding two circuits.
Problem, reading the Zs with my Kewtech loop imp. tester is OK on the traditional RCD ,as usual, but trips the RCBOs which we have only just started to fit. :_|
