Hi All
Changed a C.U today, Volex (not my choice but customer supplied it) Dual RCD, one 80A & one 63a. All test results good except on RCD test at socket outlets. on half test all OK, on 5 x test all OK but on 1 X test @ 180 no trip but fine @ 0. Ramp test ok. When tested at RCD with mcb's open they both test out OK. Any ideas please.
