Have you had many cases where it was a PS5 that was causing the tripping?

Excellent video! 100% right and big respect for not making one knowing what it will be used for!

What a load of nonsense. 500w lighting has been around for years and Ive never seen any with moisture inside from condensation.

I find the best way to deal with this issue of a difficult EV charger job is to decline the work as there are plenty of of easier jobs one can partake in.

Moisture created within the unit? That's poor wording I hope. tho the thermal fluctuations will create pressure changes draw in humid atmosphere, that will condense and build up within.

If you are installing an EV Home charger would this work?

very interesting is this a uk only problem as in the USA they fit there consumer unit on the outside and metal they don't seem to have a problem

Maybe the powers that be should think again about banning the installation of split load boards so that we have a chance of connecting to the existing cu.

I get that moisture is a risk in ip65 units. Not sure that I agree with the statement that warming air creats moisture. To crest moisture hydrogen needs to come from somewhere to combine with oxygen in the air to form h20. I believe the isdue is that warm air can hold more moisture than cold air. Therefore if air is warmed and has moisture available to absorb it will yake up more moisture. If that air rhenium cools or touches a cool surface it will release that moisture. Therefore the issue is ip65 units pulling in warm damp air that then cools to release moisture. My assumption is that the issue is more likely to come from the unit cooling down after a charge is complete, cooler air takes less space, damp air then pulled in and condenses on cold surface of enclosure. Or some simillar process.

Sorry fell asleep

Great explanation Will

Excellent explanation!

So what happens with some DIN rail products, like timers, doorbell transformers, some PEN fault detection devices, etc. where the manufacturer doesn't make a enclosure? Surely they are made to fit into an enclosure from another manufacturer?

Great video, Will. Clear and well presented :-)

Great explanation of real world conditions.

The van looks stunning Will

Hi Will. A very decent explanation of ALL but typically not my installation requirements. I'm a tme served sparky that did the 18th 5ish years ago before the new amendment about EV chargers. So trying to get all the information to install a Myenery Zappi 7kw to my existing Fusebox DB (sorry, not a Verso) and was sold a 40a rcbo with AFDD built in. Having a B curve. My board has surge protection and i have a spare way. Question? Do i need this level of protection as im told the Zappi protects against pretty much everything and the instructions with the zappi jump from saying i need a 32A to a 40A rcbo if PME. As this cost of £90 and a double pole rcbo with out AFDDis less than £20. Not fitted it yet as still learning after hours of RUclips videos and brushing up on the BS7671. Thanks in advance

Looking good

Nice

Never see a corroded one in 15 years.

Big fan of tight sheathing XD

Good stuff Will

🤷‍♂️🤦🏻‍♂️

When I saw the busbar title I got excited and thought you were finally gonna talk about double pole busbars

Installed several of your consumer units now and love them 👍

I have only fitted one of your consumer units but found the same issue on the cpc/neutral bar as others. 2nm is great but not when using a PZ/S2 screw driver and many a time I've had contactum, fusebox, hager and others deform and pit regardless of which torque driver I may use or angle that I may be using it at. Any way that perhaps a Torx T20 or T25 screw head could be used on your product instead? It sounds daft but I swapped over to Forge Fast screws with a Torx head from PZ and I'm never going back. Your unit did seem to be slightly harder to it to, only 2 out of the entire bar but it still happened, never really an issue on a fresh install but coming back to do an EICR it's a bug bearer because you're never able to get decent purchase on them after removing wires for testing and reterminating. Nice to see a silver coated bar, definitely more and more reasons to swap to your brand. Just need bidirectional RCBO's on the line up, and maybe changing it to black powder coating and green protective devices and I'm sold.

Glad I picked up on all those points when I did my video Guessed it was silver but didn’t know the reason… now I do!

Well explained

Lots of video's out there, understandably, on AFDDs and Arc Faults. As I understand it, AFDDs often have overvoltage protection. Would be good to have a video on what the benefit of overvoltage protection in an AFDD is and why is it different to surge protection. This overvoltage protection never seems to be talked about.

Great information, just going through this issue as we speak

Looking good Will

A 20 year old consumer unit with a manufacturer still taking responsibility for it, never happening. All comes down to common sense.

I would say that it depends if the manufacturer gives you written documentation that they are compatible they it’s fine, but I would be very surprised if they will test and certify it for use + it’s interest for you to have to buy another board.

And there was me thinking that they had bought out a new document that says we could cross pollinate boards 😂, great video cheers 👌

Great video. I don't like mixing brands in CUs if I can help it, but there are times when it's the only sane way. Example is an old volex board where the breaker for the socket circuit had burned out, and there was no budget for a replacement board. Sometimes you've just got to get the job done and the power back on. Have you come across any real world examples of mixed brands causing problems?

Not sure if it’s already available but would be good to have a detailed list of what is type tested to what so there is a standard that everyone can look and and say yes this is okay to use as a last resort

Thanks for such a great lesson, however I would like to know whether the spd can be of help to a circuited breaker in the event of a fault

110 VOLT SAFETY TRANSFORMERS ,can be a pain in the back side for years on plug in .

Where do ya get the hoodies from?

Thanks for the video. But Am I missing something or You have bi directional mcb (overload or short circuit ) protection You do not have bi directional RCD (earth leakage) protection. So the suggested solution does not in fact have bi directional rcbo protection if required.

What happened to verso

This was much more informative and useful than I would've thought, thanks man,

Double end

This is probably one of the best videos about the topic. New installs going forward aren't going to be an isssue as installers will generally pick a design that doesn't need RCD protection or use a manufacturer that has bidirectional RCD/RCBO's going forward. Sadly if the test button on an RCD/RCBO fails that's a C2 anyway during an EICR and when feeding a PV install it' will need rectifying with a bidirectional device in future.

I have Wallbox Pulsar Max , from what I see it does have this rdc build in , what RCD would you recommend then ? Can you give me exact model pls ? 🙏 to be installed to the existing consumer unit.

Looks very nice. I would be very happy to wear that onsite.

Have you read the BEAMA document on this? They are stating that there could be issues with MCBs as well, with back feeding affecting the arc extinguishing / short circuit characteristics.
