    Earth leakage on high loads

    Small update... I couldn't help doing a bit more investigation so I had a look at the wiring in cu. I think I'm allowed to do this? Some observations below: 1.I noticed a dead short between earth and neutral on the neutral bar associated with non kitchen rcd. However the next day when I...

    Earth leakage on high loads

    I will report back I promise. It's been very interesting investigating it all. One small update, I found 2 x surge protector 4 gang extensions and 1 ikea USB 4 gang hidden away in bedrooms. So they might have been creating some leakage. They are all binned now. I get extremely weird...

    Earth leakage on high loads

    Thanks for all the help, even though I haven't got to the bottom of this. I feel like I understand what's going on a bit more. I think what I'm going to do is get an electrician to fit rcbos to each circuit and then have all the wiring tested. I have a feeling that there's not a lot actually...

    Earth leakage on high loads

    Hi thanks for all the help by the way! It's a dual RCD CU by Harok. We had this fitted about 10 years ago but the house wiring wasn't changed at the time. Wiring in house is old Red/Black easily 20 or more years old. The RCD started tripping randomly right after the CU was fitted 10 years...

    Earth leakage on high loads

    I'd love to get each floor separated into separate rings with rcds integrated into each breaker. Maybe that would be the solution. It's going to be really expensive job though. I did find once some very old wiring with cloth insulation in a ceiling light fitting. That was replaced but it's...

    Earth leakage on high loads

    Got the square within a square symbol, see attached. So class 2? And yes plastic earth. So how could there be earth leakage? I'm confused by that. Is my clamp meter wrong?

    Earth leakage on high loads

    Yeah checked my daughters (new) hairdryer. 5ma at the plug, 5ma extra at the cu. So does seem to tally. If a single device can create 5ma leakage or even 8ma for the kettle then surely my readings of 15ma leakage current at base level is fairly normal? Turning my computers on seem to cause a...

    Earth leakage on high loads

    I modified an extension lead so I can clamp the line and neutral. Kettle did show around 8ma leakage slowly rising to 10ma then dropped to 0ma once it boiled. I'm going to try this in another house and see if this is the kettle or my house wiring.

    Earth leakage on high loads

    There's 2xrcds. Left rcd has kitchen ring. Right rcd has main ring and lighting. We also have a car charger which has its own separate cu. It looks like the earth line from cu goes to a box by the meter and here it's connected to an earth wire from the gas pipe and a wire that goes into the...

    Earth leakage on high loads

    I'll try that check and report back. With all the computer equipment off I'll check if the kettle still causes the leakage. We get quite a bit of leakage even with just the lighting circuit on. Every circuit seems to add to it. On the question about circuit testing. When we had an...

    Earth leakage on high loads

    I'm new to this forum so apologies if this is in the wrong place. I'm a DIYer, not an electrician. I have had electricians out to look at this issue and they have failed to explain the problems so I've been looking into it myself. My house has 2 rings, one is very large and covers almost all...
