This is why you should never go for a budget install! Join Lee and Luke as they conduct an EICR and fault-find on a board that's causing some leakage 😨. Dive deep into the process of an EICR and watch the experts in action. I think we can all agree with what Lee said in his rant 🫣.

I'll wager that no testing was done beyond "the lighting and sockets are working" and the EIC is a complete fabrication.

@blower1 9 ай бұрын

I can see on your Megger that you have it set to Type A mode for RCD Testing - however the board contains a CPN RC263/030 - which is a Type AC RCD. Also amendment 2 of 18th edition states AC only testing should be used to test an RCD of any type, to determine if it is functioning and tripping within the required times. What I find quite funny is you even state later in the video how DC can blind an RCD and prevent it tripping - which is exactly what you did when testing a Type AC RCD with the tester set to Type A mode. Yes the board was cheap and a bit nasty, and a ridiculous number of circuits were run off each RCD....however the RCD itself probably does work for AC fault currents, just you were testing in the wrong mode.

To be honest, start of the video I was thinking they don't understand RCD trips but Luke's rant proved that he does understand it. Trying to find which circuit is at fault if there is a N-E low resistance can be hard work, usually drop the neutrals out and IR each circuit but using a clamp meter such as shown can really help. Using it around L+N at the incomer will only show up a reading proportional to any other circuit is actually drawing power though. You could just use the clamp meter around the individual CPC/earths at the board which is the same as clamping around L+N, then again that doesn't help if the earth leak is to a water pipe. Well done guys.

Even if this is a fairly substantial installation I'm surprised there's so much combined earth leakage. Where I live (central Europe) it's still fairly common to have one whole-house RCD and I've never seen nuisance tripping like that. The one time I had utterly unpredictable RCD trips it was a faulty RCD. Old 100 mA RCD from the early 80s, tested the whole installation, IR wasn't great (some VIR circuits left in situ, came in at 8-9 MΩ) but nothing terrible. Replaced the RCD with a new 30 mA, hasn't tripped ever since.

@klapouchy1000 5 ай бұрын

We can see two RCDs, exactly as required by UK regulations, and yes, equipment used is Asian generic produce UKCA certified. Faulty RCD (and any other piece of equipment) needs replacement. In my opinion faulty RCD shall have beed replaced first and then observations made on leakage. Those observation could be improved, and Merel network analyzer unit used, or 24/7 monitoring installed (i.e. Supla), DC and AC leakage could be measured and then calculated per circuit separately. Worth to mention F type RCDs are not intended to protect from DC leakage over 6mA, and would help only when frequency is modified. That is a serious mistake. Only Type B RCDs would guarantee that DC leakage over 6mA would not block the RCD (and some RCDs type A+ used for EVSE that is still a rare product). Not sure if that job was worth 1000s...

What's wrong with that? A property with many devices can quite easily have 30-50mA of earth leakage on normal usage. Having it all funnelled through two RCDs means nuisance tripping. The 30mA trip is a safety limit to protect people. A human isn't going to have limbs long enough to touch all class I appliances in the house to sink that cumulative leakage current.

I’ll tell you a story. I went to a house where the brother in law had done a board change. The property was TT with a single rod in the garden. The brother in law had got the tails crossed when he was doing it. The home owner hung a picture in the living room and hammered the nail through the neutral and earth. The system had approximately half an amp flowing to ground when I measured it. The tragedy was the owner had 2 beautiful Samoyed dogs. When I complimented her about the dogs she burst into tears. A third dog had died the previous week from a suspected hart attack. It’s kennel was less than a foot from the ground stake. I did not tell the owner what I suspected.

@@demonkey123unfortunately one can't completely legislate against fuckwittery. A ground stake, correctly inserted, will be at a depth where there shouldn't be step voltages between the stake and the transformer. That combined with the incompetent workmanship that caused crossed polarity. That said, the crossed "neutral" and earth by nail would have caused all class I appliances and any bonded plumbing to become live as a result. If RCBOs or RCDs were installed, they'd still trip.

@demonkey123 9 ай бұрын

I agree, however my story was intended to highlight the dangers of an excessive unchecked current flowing to earth. An RCD protecting multiple circuits would only allow its maximum rated fault current to flow, while multiple RCBO’s allow a cumulative number of faults to add up to a significant amount of current flowing to earth unchecked. Using multiple RCBO’s doesn’t remove faults, it allows the system to operate under conditions that a conventional RCD protected system will not because it regards the situation as potentially dangerous.

@@demonkey123Assuming there are 10x RCBOs each allowing 29mA to leak to earth, that's 290mA leakage. What's fundamentally unsafe about that? It just means the house is full of leaky electronics. While it's undesirable, it's not inherently dangerous unless its traversing a human. Residual current devices are there to protect people. Circuit breakers are there to protect circuits. Providing the earth leakage doesn't exceed the circuit breaker and isn't flowing through a person, there's no real issue. A trip is only ever desirable if it is going to protect either a person, the circuit or both.

@@ChristianWagner888So just put some circuits on RCBOs and some on RCDs. Don't know what the regulations are regarding that over there but I have done some DIN rail control panels with RCDs and RCBOs in the US, and I will group together several circuits on an RCD if I want all of those circuits to trip if one of them has too much leakage (for example, for a PLC with inputs fed by different circuits or systems), but I will also install an RCBO if I want that circuit not to trip the common RCD (For example a large air compressor hooked to metal piping). Seems to me that this board could be fixed by reducing the number of circuits on each RCD, and putting in RCBOs for the circuits taken off. Done strategically this could be less of a hassle for circuits that commonly trip the RCD.

Is a split RCD board ever the answer these days compared to an RCBO board? Having worked on and installed both I find the RCBO board to be much easier all round, and I find it hard to believe that the overall cost will be much less with the split RCD board. With a decent quality but low cost RCBO board like the ones from Fusebox, what sort of difference in price are we looking at for say a 20 way board install compared to a similar quality split RCD board, both running type A RCD/RCBOs? It can't be more than 10 or maybe 20% surely?

@@SBBUK Yeah I know... But in this case, surely if the spark had told the customer the reality of how many circuits will be lost just because one of them has a fault, then you'd think the (IMO) relatively small extra cost could be easily justified. Not to mention the cumulative leakage causing nuisance tripping. But that assumes the spark actually cared which seems unlikely, although it's unfair to speculate around the circumstances which led to this rather poor design choice. Obviously some people have no choice but to go for the absolute cheapest option, but that house didn't seem like somewhere you would install the cheapest option. Then again there are people who own fancy cars and install cheap tyres made of chinesium and wonder why they can't keep then on the road! I reckon kids should be taught about "value" as a core subject at school. Not just low vs high cost but actual value!

For EMC compliance class X and class Y capacitors are fitted between L, N & E. Each device (PC PSU, audio equipment etc) may add a few mA to earth leakage. I was involved in the design of a large non-domestic LED display where we fitted 32 off small DC power supplies. Each had it own EMC capacitors, and a soon we tried to power it up, the 30mA RCD on the supply tripped. We had to remove the internal EMC filters and fit 1 external EMC filter to each set of 4 PSUs. At home I had a cheap Tesco DVD player. It had a two wire mains connection (no earth), X capacitors to its metal case, and a switch in the neutral. When it was "turned off" one could get a slight shock due to the L-E capacitor. I notified the supplier of this design fault, but had no acknowledgement.
