Hello
I hope someone may shed some light on this problem that I looked at today.
A number of 30mA RCD twin sockets (Timeguard passive) on a reception desk, fed buy a local DB which is UPS fed, keep tripping every now and again , with only one item plugged in to most of them , one had only a double insulated power supply for a phone.
I ruled out earth leakage of the plugged in devices but wondered about the if the UPS supply was to blame? I have not tested the loops at the sockets at this stage but I am sure that they will be ok as the DB is new as is the sub main from the UPS MCCB panel and final circuit.
I was thinking of replacing the socket with another make like MK to rule out a problem with the sockets themselves.
Any one else had this problem ?
