In the process of installing a new Consumer unit. (Contactum 10way split load) Just got power and the main earth (6mm earth from incomming cable lead sheath to be replaced later by PME) connection onto it at the moment but the test button on the RCCB (30mA) does not cause it to trip. Anyone know of any reason, other than it's DUFF, for it not to function ?
thanks Ady
