Do I require a fuseboard ?

[rockman]

Hello there, can anyone tell me to which regulation I should have a fuseboard ?
I have looked at Reg 533.1 but it does not say I cannot have one to a different regulation number.
The scenario is thus:
A council run block of flats.
It is an outside scenario in a mains cupboard.
It is supplying outside lights from a fused spur.
It comes directly off the mains supply to a main fuse to BS88 supplied by the electricity company.
To an ordinary switched fused spur. (In double insulated cables (6mm with a 10mm earth)
From here it travels in the wall to a set of outside lights high on the wall.
Can anybody tell me what regulation we are breaking.
No smart answers please.

Are you an electrician? If not I would suggest you get one in, lots if different reasons for your install

What is wrong with the answers you had here? http://www.electriciansforums.net/i...-installations/74775-new-here.html#post746285

533.1 has little relevance, it is just the different types of acceptable fuse.Why do you think it is wrong?You said it is off a fused spur - couldnt that be classed as a one way fuseboard?It certainly allows isolation and over-current protection.Oh, and a smart reply, you cannot get 'double insulated' cables.

April fools???

, you cannot get 'double insulated' cables.

So what do you class 6242y as?

 

[alanl]

It is protected, and can meet the requirements of double Insulation, , but cannot be classed / marked as 'Double Insulation'. 412.2.4.1

So what do you class 6242y as?

insulated and sheathed. the outer sheath on 6242 is an insulator, but not classed as such. similar to some tools. they're insulated by means of plastic handles but not tested to 1000V and not classedd as VDE.

Fair enough everyday is a school day.

What size is the bs 88 fuse?

No smart answers please.




smart answer.

 

[rockman]

What size is the bs 88 fuse?

60 Amp but that shouldn't matter due to the close proximity of it.

 

[odawire]

60 Amp but that shouldn't matter due to the close proximity of it.

Ird say that if the fuse is acceptable for the cable then it sounds ok, I cant be bothered to look it up but 60amps sound a bit high for a 6mm t+e

Sorry to the OP, no you cant. Its for outside lights and needs to be on an RCD/RCBO. Get an electrician to do this so it can be tested, certed and notified.

I might be wrong but I assume he is talking about an existing installation

 

[Paul.M]

I've re-read the opening post, doh.

A switched fused spur can be used as the isolating switch if it is in a lockable enclosure. If not then a lockable MCB/RCD must be used so the circuit can be safely isolated so it can be worked on.

You don't require a fuse board as the lighting is "run" by the council why don't you speak to them ? And let them decide, and yes, this is a smart answer. I, we, they are responsible for the external lighting.

If you are suggesting that the reason for an RCD is 'outside lights' you are mistaken...there's no specific requirement for external fixed equipment to be RCD'd.....OP states 'cables in wall'...a bit vague but may or may not need RCD protection depending on installation method.

Yea but its existing anyway so def no need for rcd protection at all

Unless it was installed after 17th ediotion cae into force and doesnt comply with 522.6.100

We don't know when it was installed

 

[Plonker 3]

Thats my point.

 

[odawire]

Surely in a real life situation you would assume it was done before 17th edition?

 

[Plonker 3]

assume= --- out of U and ME

Never assume anything it is a dangerous thing.

 

[odawire]

fair enough, but unless theres information or evidence you have to assume 1 way or the other

 

[Plonker 3]

I would call it professional judgement. There are usually several different signs to the determine the age of a install. Not everyone knows them, there fore that is why I would call it that.
