Magnetic field effect on a lighting circuit would be way too small to be an issue. My steel CU has tails coming into two seperate holes - I checked with a thermal camera with about 35A load and saw no measurable temp rise. It might be an issue on heavy duty industrial setups but insignificant in a domestic situation.

[@callumBee]

JW did a video on this with 100s of amps and there was no real considerable temperature rise.

[@ColinRichardson]

@@callumBee good olde JW

[@MrKarlPrince]

A rise in temperature is more likely to come from the resistance of a cable than induced eddy current in consumer installations

[@Chris-hy6jy]

The whole "tales through separate holes" thing is a complete non-issue. It's just yet another stupid unnecessary regulation. Got to keep the regs people in a job I guess! 🤦‍♂️

yup. And if your gonna use the wander lead, use a multimeter on continuity reather than waiting around with the tester.

[@damienhanson4929]

Singles is another good way to keep amount of cables at light fittings down. Neutral in neutral out and one switch wire. Permanent singles feed to switches only and switch wire up to light.

[@colingreenwood987]

Here in Aus, SDI cable is dearer than twin actives. We always run the 2 core. At worst case there is a spare for any future upgrades or faults.

[@acelectricalsecurity]

It's always done that way in conduit, not that common outside of a conduit system, would probably be more expensive these days as well.

[@Bin216]

The armoured cable: gland the armoured cable into a non-conductive box/conduit, and label as “Caution: Independently earthed at remote end. Do not to connect to local earth.”. That way you have shown that you could have connected the earth, but not doing so an obviously explicit choice rather than a potential cowboy installation.

[@9plusinstalaciones]

Eddy currents on a single cable going through a metal hole really wouldn't be an issue.

[@tobysherring1369]

John Ward tested the effect when tails are put through separate holes in metal. There was virtually no effect at the sorts of currents carried by tails, so you don't need to worry about a lighting circuit. It's certainly not "against every reg."!

The extension on my house uses single & cpc cable for the lighting wiring. Makes a change from the VIR single (no cpc) used for lighting in the original part of the house. Edit: I wouldn't worry too much about the magnetic field associated with single cables. John Ward did a video on the subject and showed that unless you are passing ridiculous amounts of current through the wires it really is a non-issue.

[@AndyK.1]

They did do pvc with no cpc. Double insulated. In the 60s

[@jensschroder8214]

I made a change a few years ago. It was on a staircase. First the cable came from the fuse and went through the on-off switch and from there three-pole cable (hot switched, neutral, earth) to the lamp. It was all already built. Then it should become two switches. The switch was exchanged for a pushbutton. I had to get hot again via a separate cable. Neutral and earth from the old cable. Everything in one big box neat the lamp, the old cable from the first push button with neutral and earth, the cable with the new hot, the cable to the second push button (hot and switched), the cable to the lamp and an impulse switch. It was easier to change the cable closer to the lamp and from there to connect the second pushbutton and impulse switch closer to the lamp. But I needed the hot without a switch via an extra cable.

[@projectartichoke]

I had knob and tube wiring like that for old three way switches in my house. Of course everything was single conductors, but usually two were run near each other.

[@Satters]

6241Y is used in 2plate wiring Neutral looped around the ceiling roses, Line looped around the switches, exactly as it would be in conduit but in sheathed wiring, instead of 3plate loop in wiring using 6242Y where line is also looped at the ceiling roses the more common method of sheathed wiring

[@Marcel_Germann]

That's all around the world with building in a neat new board, but you still have a mess of old crap work around it. And here in Germany that's also a thing, especially due to that it was permitted until 1973 (in East-Germany until 1990) to have TN-C in final circuits, so no separate CPC, instead you got a PEN there. You can't install modern RCD protection in such old circuits, all RCDs and RCBOs we use here not only switch off the line, they also switch off the neutral. And it's not permitted to switch a CPC or a PEN. And as long as the installation is still intact and meets the requirements from back then, you can't force the owner to replace it. You can only recommend a modernisation. The only thing you can do is implement MCBs only in a new board, and on extensions be creative and implement something like an outlet with integrated 30mA type A RCD, which is btw. far more expensive than a rail mounted RCD (material cost is round about 130 Euros for them), and split the PEN from there into a separate neutral and CPC and then at least the extension is meeting modern standards.

[@Ragnar8504]

Yeah and in the part of Germany that used to be behind the Iron Curtain, TN-C with 2.5 mm Al wire was permitted until 1990. Plenty of that still around! Only kitchens and bathrooms required RCD protection from 1984 onwards and were therefore wired in three core instead of two core (black and yellow/green).

[@SuperUltimateLP]

A way bigger epidemic is the Fakt that there are still so many houses in Germany that still have the type "H" resettable fuse. (A relic from the 60-70s they stopped selling them in 1977) So many houses could be saved from burning down if there owners knew what the heck is in there fuse board.

[@Ragnar8504]

@@SuperUltimateLP H-curve MCBs have rather poor overload protection (thermal trip) but that's something they share with their successor, type L. Combined with the German obsession with putting 1.5 mm on 16 amp MCBs that can cause overheating. The same is true of Diazed/Neozed gG/gL fuses BTW! The main purpose of H curve MCBs was offering fault protection in TN-C(-S) systems with high Zs, the magnetic trip is very fast at 2-3 times rated current. Of course that's quite annoying if you're using anything that has a high (-ish) inrush current, especially motors. The Austrian regs recognised the overload issue fairly early on and reduced the maximum overcurrent protection size of 1.5 mm to 12 amps under most circumstances, along with the introduction of L12 A MCBs in 1980. This historic relic is the main reason why B13 is still the most common household MCB size in Austria, even though the regs now allow B16 for 1.5 mm unless the cable is embedded in insulation.

[@SuperUltimateLP]

@@Ragnar8504 i wouldn't call it a obsession ;) I my self only use neozed fuses as a prefuse not as a primary. People tend to screw in what ever fits even if I install a ring (don't know how to say it in english) to prevent the wong fuse from being inserted, idiots pull them out and screw in a 63A because "the previous one was obviously to small". 1,5 is to my knowledge only allowed for lighting and low usage circuits. Everything thata has high power draw needs to be 2.5 for example washing machines/dryers.

[@Ragnar8504]

@@SuperUltimateLP With some electricians I do feel it's a bit of an obsession :-) The VDE regs let you have 1.5 mm on a B16/C16 in some circumstances - installation methods Bx (singles or cable in conduit) or C (cable on or in wall), two current-carrying conductors, no derating for bundling or higher ambient temperature. Despite the fact that most new construction is all method Ax (singles or cables in conduit in insulation, cables directly in insulation), 1.5 mm and B16 are still the most common choice in German domestic electrics. Apparently at the onset of WWII the current-carrying capacity of 1.5 mm Cu/2.5 Al was increased to 16 amps in order to deal with wartime shortages and that change was never repealed. Eventually, manufacturers pushed 16 amp MCBs in such quantities that they were discounted heavily, eventually giving us the "€ 1.99 B16 single-pole", which in turn caused electricians to use only B16s because everything else was at least twice as expensive. Conscientious electricians will use 2.5 mm for high-power loads but 1.5 mm can still be acceptable. Besides, most modern washing machines and dryers don't exceed 10 amps, even some ovens don't. I recently looked at a used IKEA oven from the late 2000s and it was less than 2 kW if I remember correctly!

I think at 3:25 Cory is right. In the UK the left-hand-rule should apply, while many other countries use the right-hand-rule, so either rule is in sync with the traffic on the streets. Otherwise the magnetic fields would't cancel out with the cars, driving on the other side. Trust me, I'm an engineer 😏

Magnetic coupling is an issue when using metal containment. It may not cause a noticeable voltage but 2 things come to mind. Inductive impedance and corrosion.

A lot of new houses lighting circut were wired in single and earth in my time as a electrician on large building sites .

[@havoctrousers]

I did a 1970s house the other day where they'd used sheathed singles for the lighting. CPCs were their own singles to the luminaires, but no CPCs had been run to the switches. Switch returns went straight to the fittings in a sheathed single and there was only one "junction box of doom" per floor to connect all the CPCs, neutrals for the fittings and the perm lives down to the switches. Quite an efficient use of cable and JBs, but a bit of a nightmare of ripping up floors if you don't know where that junction is.

I work in council houses and they still spec lighting circuits in sheathed singles. We use live and earth, and separate neutrals. The lives loop around all the switches and the neutrals loop around all the lights. Obviously in council houses they don't expect people to be fitting smart switches etc so neutrals at switches isn't a consideration yet. Strappers are done in twin and earth. Out of interest you used to be able to get red sheathed red and earth. They used this as permanent lives, then normal grey sheathed red and earth for switched lives. Then you could tell at a glance what was what in your switch drops. We come across a lot like this wired in the early 90s.
