It's Fuseboard Moving Duty | Thomas Nagy 

Excuse my ignorance, but why should be there any heat to dispense, unless there is something wrong, like loose connection. Flow of electricity can generate heat but in a 100A installation even in maximum demand it's negligible if the design and installation are right. Regards

Absolutely

ditto , bootlace crimps

"dedail" lol :-)

132 Buckleup1000 It’s accessible and doesn’t contain any e mcbs so it’s fine.

Why does it need to have mainteance free connections when it's easily accessible?

IMHO there are *NO* maintenance free terminals.

Cute, bro, the term is "cute" ;)

Awh haw

It's not a fuse baord...

No it’s not a zip tie, it’s a zippy tie 😀

I dont think you should cut down any of the leads of an RCBO personally since they are manufactured to operate with that cable length despite only a slight change when cut down realistically however im only sn apprentice so take it with a pinch of salt

@@liamhammond6043 You would need high grade lab equipment to tell the difference , the RCBO is not going to know :D

@@liamhammond6043 The measurement happens inside the RCBO, its nothing to do with the external cable its just an external extension of the Neutral.

They come in "rainbow" order - resistor colour code. Numbers are printed on them.

so yes you can cut them

I don't think there is... But remember BS 7671 is the minimum standard, you can always go above and beyond the minimum.

The only true advantage of RCBOs over RCDs is that in case of an earth fault only one circuit trips rather than half the place or even all of it. I'd like them but considering the prices it'd probably be cheaper to get a 2-pole RCD and MCB for each circuit rather than an RCBO round here. Besides, in Austria there's still an ongoing debate whether it's acceptable to have overcurrent protection and earth-leakage protection in one device (backup protection in case of a defective RCD in a TN-C-S installation is the MCB and the reasoning of some is if both are in the same moulded case, both could fail at once).

So, if some RCBOs are type A and some RCDs are type AC, it doesn't mean they're all the what they're specified to be?

@@Ragnar8504 also the advantage when used with equipment that has a natural earth leakage the 30mA is per RCBO, not 30mA or 2x30mA (60mA) per installation!

Ragnar8504 - eh? A RCD is not a over-current protection device, and a MCB will happily let its rated current flow to earth, only tripping if the current goes significantly above its rated current. So I don’t see how separate RCD and MCB offers greater protection than a RCBO.

So, tell me, is it within the standards to use normal socket outlets in the plastic wall trunking (the type that can take accessories)?

It's possible to overload the main fuse using a two-way board (e.g. 60A main fuse with two 50A MCBs). You have to do a calculation of the maximum demand of the installation, but you can apply diversity within the calculation. Diversity is the concept that not every item of electrical equipment is in use as the same time, hence every final circuit will not always be drawing the maximum power it can. There are set formulas for the diversity on different sorts of final circuit.

The incoming supply is 100 amps. You're very unlikely to be using the full 100 amps all at oncebut you'd factor in diversity of loads. Electricians don't usually have to calculate diversity on a residential install and they can just use their intuition and for anything industrial, the electrical engineer will usually have calculated diversity in the design of the system.

If both boards come with the labels, it can't do any hurt to use them.

No, just 1 set will suffice, they dont have to be on the boards either, they can be at the origin of the supply. Because they contain the words "This installation" it covers the whole thing

I'd like some Love too as I've been subscribed for months :D

It’s a fab idea! MK are you listening?

Not a spark, but when replaced my own CU I went with grouping the breakers by area of the house. Eg 'upstairs' will be one bank, 'downstairs' another, with a separate bank for the kitchen. ...I had a mate of mine who is a spark test & check all my work then sign off on it.

To avoid unnecessary heating of the bus bar the highest go by the main switch.

I'll do one

@@thomasnagy Thanks Tom, great work! s. :)

i think mrs nagy would not be happy if that was the case.

@@thomasnagy You're lucky! Soon-to-be Mrs Void wouldn't be happy if I complimented another girl like that haha

They`re numbered markers to make it easy to tell whats what in the big terminal box he`s installing too, www.hellermanntyton.co.uk/products/wire-and-cable-markers/wic3-0-9/561-03100 1 in the consumer corresponds to 1 in the Junction box etc

semi tighten...then tighten once the board is finished to specific torques ;-)

@@muzikman2008 "Oh yes, I'll come back later and torque it up" 😂😂😂

Actually it is easy to get them since the UK is still in the EU. Here in Germany the installation of type AC RCDs was banned for new installation already in 1984, for the obvious reasons of getting problems with switch-mode power supplies which were upcoming at that time at a larger scale. Standard here is the type A. You can use your UK amazon credentials on the german amazon site (amazon.de), search for RCD with the fitting tripping current. They will ship it to you without additional costs, but if you got prime, this won't arrive the next day. For example this one here: www.amazon.de/Eaton-236748-FI-Schalter-40A-30Ma/dp/B000UW4EGE/ref=sr_1_28?__mk_de_DE=%C3%85M%C3%85%C5%BD%C3%95%C3%91&keywords=rcd+30ma+40a&qid=1565731567&s=gateway&sr=8-28 But I would only do this if there's no other alternative to this, for example you don't want to change the whole board just simply replace the RCDs. It was not mandatory to replace all of the AC RCDs, it was only not permitted to install them in a newly built electrical installation. And when the old ones caused problems (tripping below 50% of the tripping current), they were replaced by type A. So no additional costs to customers.

It’s a DIN rail, all it does is hold the breakers in place. The busbar which feeds the current through the breakers is covered by a panel and the fuseboard cover when in use.

The busbar... and no it's not insulated, there's usually a shield or barrier you fit just in front of it before energizing.

I try to massage the extra cost in your price somehow; but you can’t always get away with it.

Thats at least "16th edition" or older. Nowadays, "18th edition", in a domestic installation every circuit must be protected by an RCD more or less. There are multiple ways of achieving it, A separate RCBO for each Circuit is the best but also the most expensive, which not many people are willing to pay for. When a fully populated 10 way Dual RCD split load board can be bought for under £100, but RCBO`s are around £30 each + the Board it soon adds up

They`re just the IMO ones that are usually on a stand in the showroom of most wholesalers, or you can get them in boxes of 100 from Lockwells etc but then you have to buy end plates etc too heres a few uk.farnell.com/c/connectors/terminal-blocks-accessories/din-rail-terminal-blocks?brand=imo-precision-controls

Cheers chaps 👌

Use wago din rail blocks. No screw terminals they just have spring retention and you just slide a wago tool in for assembly. Lots of sizes and configurations available. Buy a full kit and it comes in a posh Bosch L boxx

Correction... I've just seen a previous video with your knipex cutters 😔 Must try NWS though

I thought the same, I half expected Dave to sit around with a cuppa just to take the piss 😂😂😂

"He doesn't mind taking his time dressing out a fuse board over the next six hours." -Tom What I hear is, "Dave needs to move his ass more."

TheCod3r Tutorials I’d easily do that just to take the piss haha sry Tom 😂

Snarky Mark CUs are complex items. The wire bends need to have the correct radius otherwise the electrons won’t flow out. 😂

Fix Radio ... of course!
