direct burial cable - not in conduit- also 2 wires in a breaker's lug ???

[1capybara]

Is SWA [BS5467] the only type BS or CE or IEC cable that I can direct bury -
not in conduit?
also: is there anything in 17th edition that says I cant put 2 wires in a breaker's
lug if they fit?

It's electrical art to see a good MI installation, I'll have to dig out some boiler house pictures that I keep in my 'electrical ****' collection, I'd like to say I installed the MI but I only took the pictures....

These skills are slowly dying even along with good trunking and tray fabrication.

You can see the term 'modular pre-assembled' taking over in our trade, on-site construction and installation will be phased out on new projects over the next few decades.

Wouldn't he fall foul of regulation 314.4 regarding each final circuit shall be connected to a seperate way in a distribution board. As an EIC is for a new circuit. Did he square that one off.

He wasn't being all technical and say that a CU is not classed as a distribution board as such was he?

Spoke to a chap at the IEE the other day about something similar to this - was putting a light in the cupboard under the stairs beside the CU and just putting it in beside the existing downstairs lighting on the same 6A mcb. I had assumed it would just be a meiwc but he said it would count as a new circuit! So what would you give for a spur at the origin on a ring or radial, minor works or eic??

That's rubbish, define 'a circuit '

By that logic, you'd show emergency lighting doubled up at the mcb for the primary lighting as a separate circuit with separate certification!

There is no regulation on cables at mcb's but the limiting factor will be the integrity of the connection.

I used the IEE email service just to try it out and see how quick it was and asked "When installing a single light fitting close to a consumer unit (actually in cupboard under the stairs) is it ok just to fit the cable staight from a 6A mcb already used for lighting and would you use a minor works cert"

reply from senior engineer was You would not use a minor works if you are connecting to the MCB as you are constructing a new circuit (even though one already exists for the old lighting circuit).

So i take it, like me, you would go with a meiwc for the lighting and a spur at origin of a power circuit.

i would disagree with him there. if you are adding an extra light to the existing lighting circuit from the same MCB, then that new light becomes a part of that circuit.the circuit starts at the "live" side of the MCB, simply because that mcb ITSELF IS PART OF THE CIRCUIT. So, IMHO, he's talking a load of IEE boll***s
