Only useless videos get lots of views and subs, Unfortunately. What he is showing here could save hours of agro for someone..I found a wiring fault once..it was agonising, fault in loop due to poor construction of the extension wall. My friend was going spare. Luckily I traced the faulty loop using a DMM and process of elimination, other electricians could not locate the fault and gave up. I learnt a few things and felt humbly happy. I admire the patience that good work people have.. Thanks for the video 😊

My 10ps worth: The common neutral bar can throw any 'MCB switching' RCD trip test. A low L or N in an 'off' circuit can cause a trip in an other healthy circuit through the neutral bar and any connected loads. The only sure way is to isolate all neutrals from the outset.

The reason why you should measure isolation resistance while having the earth connected is that there could be leakages to earth that don't flow via the CPC wires. Consider the example of a damaged cable where the live wire touches a water pipe, but the CPC doesn't. When you measure between live and CPC, without connecting CPC to the earth rail, you won't find this fault.

Once pulled a board up with 5cables running on top of joists nailed .We only had a 500v Megger to locate faults .Made your brain work to think outside of the box . Was interesting in my day.

I love seeing how things are done in other parts of the world. Seeing what's different and the same is quite fascinating to me. I like and dislike DIN rail distribution boards. I like the standardization and the configurability but I like the plug-in breakers that are the norm in North American installations because they result in a cleaner install with fewer cables. We do a lot of other stuff differently across the pond too and it isn't just our odd 120/240V "split phase" system that's a relic from the Edison days. First thing is that we don't have big ring mains with fuses in the plugs; everything is a radial or "branch" circuit. In the North America, the usual Class A Ground Fault Circuit Interrupter or just "GFCI" is a 4-6mA trip device intended to protect people on a single branch circuit. There are 20mA and higher equipment protection GFCIs (sometimes called Ground Fault Protection for Equipment, GPFE) that are similar to the RCDs in this board, but these aren't generally seen outside of industrial applications. Circuit breakers with GFCIs (an RCBO-like device) have been around for decades but are only recently becoming more common in the USA now that arc fault protection has been made mandatory on almost all small branch circuits in homes (15 and 20A 120V) due to the advent of dual function breakers that combine an AFCI and GFCI in one device. With that said, GFCIs built into receptacles are still far and away the most common way of adding this protection; the GFCI sockets with the test and reset buttons are all but ubiquitous in bathrooms and any other place that might get even a bit damp. One thing that's not different: Our displeasure at that unserviceable LED driver! That LED driver unit concealed behind the tile would be a violation of the NEC in the US. The inspector would be displeased and would make them fix it.

Nooo problem in being "over cautious" imo wrt isolation, Tom. Better to check several times than to cock it up once. You are right about overtrousers etc making you sweat, also when you take them off, you release all of your trapped farts! Well done on all the stuff regarding WAHR. Loads of potential risk at height, but should be no problems if managed properly. Problems start when people get blase or lazy. You were right to point out other truck. It may be seen as "grassing up", but it may ultimately save an accident or fatality. Arguably, under HASAWA, if you see something wrong, I suggest you are pretty much obliged to take some kind of appropriate action. Many accidents happen because people "turn a blind eye".

BTW having the CPC's in the the IR test also picks up if there's a fault between live or neutral and something bonded, e.g. a cooker cable chafed against a gas pipe. I start with them in, then pull them out if there's a fault to rule out that issue.

You could maybe use heatshrink butt splices for those shower lights. Crimp the wires then heatshrink to form a seal. Molex do a series called 'Perma-Seal' that cover a range of wire sizes. Needs a crimp tool and a heat gun but the end result is a reliable, sealed joint that doesn't take up much space and should last for years.

It has an old VOELCB on the TT supply to the board, that tripped as well. Im replacing that with a 100mA RCD & Isolator, fitting a new earth rod, as the only earth they have is gas bonding (which as we know is not allowed as a main earth) no water bonding, and the existing earth electrode is buried under a block paved drive lol.. and its open circuit somewhere, I like fault finding 😂 but i think i have opened up a acan of worms lol.

It's just a technique I developed as i've come across faults before where the line or neutral has made contact or near-contact with structural earthing and in one case even a bare bonding conductor in the ceiling void. Gives you a better idea whats happening right off the bat.

IP ratings, the 1st number is the dust (solids) ingress and the 2nd number is the water ingress, so if you need an X4 rated fan, you can have X4, 14, 24, 34, 44, 54, 64 or better. the X4 normally denotes that it hasn't been tested for dust (solids) ingress, but I am pretty sure that you can install something of a higher standard. the 4 for water (liquids) would be that it has been tested to resist water (liquid) ingress for splashes for 5 minutes from all directions with a flow that doesn't exceed 10leters per minute at 80-100 kPa. what would normally be described as "Splash resistant"

@AdrianBawn2 жыл бұрын
This is correct. First digit is for physical particulate protection. Second is liquid ingress. In most cases, if its X4, you don't need to check the X as particles wont get into a splash-proof container. And even if they do, its likely not going to affect the operation of the fixture significantly. That said for fitting inside the shower cubicle i would be looking at X5 or better tbh, as directed jets of water are possible.
