I've had a recurring problem with my fuse box RCD tripswitch tripping overnight and I'm wracking my brains to find out what's causing it; thought I'd post something here to see if anyone had similar problems before I fork out for a leccy.
We're with OVO and have had our smart-meter for about a year, which replaced our old manual meter. Our fusebox is a Memera 2000 and the RCD protects our shower, water heater (defunct as we use a combi boiler which is wired to the main supply) and sockets (all on seperate trip switches). During the night the RCD switch will trip which knocks out our power so I have to turn it back on manually in the morning.
I've used the OVO energy tracker to trace the problem to when it started on 14/06, where we had readouts of 0.0kwh at 2.00am. It's a pretty consistent pattern with a few minor variations which I've listed below
19/06 4am, 20/06 1.30am, 22/06 2.30am, 23/06 2.30am, 2/07 13pm, 3/07 3am, 6/07 2.30am, 7/07 4.30am and 8/07 4.30am.
I've gone through several steps to try and isolate the problem such as
* turning off all appliances overnight
* isolating shower, water heater trip switches (can't do sockets as that controls the fridge)
* bought a new fridge to replace old one
* ran new fridge through extension cable to different plug socket overnight
* turned off combi boiler overnight
* turned off house thermostat overnight
But nothing seems to be working. I'm considering the possibility it's the fuse box itself, or possibly the smart meter, but considering it happens around the same time most nights I'm thinking there must be something on a timer that starts running an unusual currant around that time in the morning. Can anyone help me out as I want to know everything I can before I have to get an electrician in?? Thanks in advance.
