RCD switch keeps tripping

Turn off all the socket mcbs. Then see will the RCD reset. If so, turn on socket mcbs 1 at a time and see will one cause the RCD to trip.

Make sure your immersion is turned off

Why do you say it’d indicating down stairs sockets

It’s most likely a neutral to earth fault

it doesn’t necessarily mean that’s the faulty circuit

it may trip when it’s drawing a load

move an appliance up stairs and try it in a working socket (kettle or toaster) and see does it trip

also turn your heating off (sometimes the pump may go faulty)

Theres a big chance that its sockets in the shed, connected to the downstairs sockets line.

How your fridge? We had an rcd fuse tripping, at first it was once a day for 2-3days, then the frequency increased to every 30mins. Found out that it was something connected to the sockets and then my daughter asked me if I can fix the fridge? Problem found.

Try disconnecting everything downstairs. If its still tripping, then probably its sockets in the shed.

If not, them try connecting some appliances, fridge, tv, broadband router etc...

what is connected in the shed?

disconnect everything and check the switch again.

Hi, I have an armoured cable.gojng out.to a garden room. Only there's a join in it, under the garden.

When it used rain heavy, it would trip and wouldn't let a reset until it had dried out

Three months ago I did a job on it, got a real ip65 junction box. Thr other day, it tripped again, for thr 1st time

Now it keeps tripping, but unlike before, it will stay on for 15 seconds and then trip. Is it the same issue? Seems more like load?

Have a very good junction box, looking to get gel to fill it

Hard to purchase

Gonna pump this in to a wiska box

I've yet to take a look, but was with previous box

Hi, definitely moisturise in the box, it had a load of visible water in it. Dried it and sorted. Here's the stuff I bought
