Fused Spurs

[Kate Scorey]

I think I'm about ready to blow my own fuse right now.

 

We are in mid discussion about Fused Spurs and the NSI rules and regs regarding them.

 

We have one person saying... it just need a competent person...to install it.

 

Then the rest of us are saying it requires an electrician or a member of our staff that have part P.

 

Can someone clear this up. Before I loose the will to live.

 

What do you all do?

 

We have been on the phone to NSI who seemed a bit lost. So we contacted our local electrician company who said the majority were correct.

 

Any help guys?

There is absolutely no requirement for any additional fused spur being added to a ring circuit or lighting circuit to be doneby a Part P bod.

 

But it should be a competent person and should be certificated for the tests that were done.

 

Obvious exceptions would be;

 

Domestics in a Bathroom or when any part of the cable runs outdoors with a junction box also being outside

 

Connecting direct to the CU

 

and prob lots of others....

I thought competant was limited to your own property?

[9651]

nope

 

You done need to be qualified to be an electrician, just competent.

 

Under the scope of competent, the only way to "prove" you are, would be works done follows 7671.

 

So thats where all the paperwork comes from.

Copy of a reply from NSI when I questioned certain lack of testing etc in a previous employ.

 

Where an alarm company installs a fused spur, it is important that the electrical safety of the fused spur and the fixed electrical installation supplying the fused spur should have been checked.  Thus, the alarm company should carry out the appropriate BS 7671 inspection and tests on the electrical installation of the building.

 

These electrical safety checks include inspecting and testing the main earthing arrangements at the main distribution board of the building, including the main equipotential earth bonding arrangements, inspecting and testing the means for automatic disconnection of supply (fusing or circuit breakers), etc, as well as checking earth loop impedance, and polarity at the fused spur point.  (Please note that I am not intending here to give a full list of the inspection and testing needed; simply to say that it will need to include these matters, among other matters).

 

I would suggest that some of the inspections and tests on the electrical installation of the building may be best done before the fused spur is installed, in case there are electrical safety issues to resolve within the building.  It is of course necessary to carry out all the necessary electrical safety checks after the fused spur has been installed.  Records of these checks would need to be kept and a minor works certificate would need to be issued.

 

Please note that electrical work in dwellings now falls within the scope of Part P of the Building Regulations under which certain work must legally be notified to the relevant local authority.  For example, this would apply if the fused spur is being run from a separate way (i.e. as a new circuit) from the distribution board.

 

Yours sincerely

Just back from a meeting this afternoon were this was brought up. Basically site has an intruder alarm installed by national company we have won tender to install a smoke cloak in all sites it was suggested we add spur unit beside each IAP panel spur and spur off into  existing can my guys do this without issuing a cert for adding to circuit?

We have 2 or 3 electricians who we work with and they will always put the spurs in for us and test.  I actively use the fact we do not install the spurs (as we're not qualified and/or more importantly competent ) and those other firms just chucking in spurs are probably breaking the law.

 

Those non-electricians who install spurs - do you test the work you've done and do the paperwork etc?  Thought not.

i doubt anyone does that,most alarm engineers dont have the gear nevermind knowing what type of supply or earthing arrangement is coming into a building,best to get a spark into do it saves the hassle

No part P in Jockland!

Any modification to the supply side would/should need a minor works.
