BS 3036 fuses not allowed for new circuits!!

[HappyHippyDad]

This is what my assessor has told me!

He states that the BS3036 does not meet the 0.4s disconnection times and cannot be used for any new work.

I do not have a BRB so cannot see the disconnection times for a 3036.

Surely he is wrong? He is suggesting that we have to change the 3036 if we want to carry out any work.

Bit cross... I did not like him at all.. different bloke to last time!

.....

sorry, I do have the disconnection times for 3036 in the BGB...but surely it's dependent on the Zs?

One thing I would say is that if you are going to extend a circuit protected by a BS 3036 fuse then the correction factor of .725 would have to be applied to this circuit . the only thing I would do is to use a fused spur to feed an additional point or RCD fused spur if required ...

 

[SPARTYKUS]

Yep me too. If thats whats required.

HHD next time you meet that assessor, ask him how he feels about 13A fuses, and the like, as they are effectively just like a rewireable, as in, a bit of "fuse wire". Ask him if he thinks every house in the country needs a circuit breaker fitting at the service head instead of that silly great fuse wire thing.

 

[telectrix]

You can use any protective device so long as you meet the disconnection times. BS3036 fuses are still listed in BS7671 so as long as the measurements and calculations work out, they are fine.

until some complete moron of a customer fits a nail in.

Late to the debate, but totally agree with the consensus, the assessor is wrong. As has been stated, if the circuit Zs falls below the adjusted max Zs value (0.87 for 30 amp, iirc), your good to go.
Oh, and ask him which Reg he is using to justify his comments.

In the new 3rd edition/cash cow if you added a circuit to this CU would have to add a RCD or do it surface glav or in glav in the fabric of the building or more than 50mm deep in the building. And this is the best in a building with an electrically skilled person you have to do a risk assessment to say, why you deem it safe not to have a RCD.

2nd bit in bold that's just for a socket outlet without RCD protection and if the installation requires RCD protection then you would have to put it on a RCD anyway.

And the 1st bit in bold you should already be doing this anyway but doesn't have to be galv when surface.

and yes the bloody ZS values or down again to suit them EU counter part muppets. so if it passed last year buy 10% it will be a C2 next time.

Jesus glad I'm not one of your client using a Regs book which as been out of date for 3 years

Not sure what you mean by 'adjusted max Zs' Polo? Page 55 BGB has the max Zs for a 30A BS3036 as 1.09?

Are you referring to appendix 14 BGB?

I dont think you quite understood the sentence. I have BGB.thought the 3036's would only be in BRB

And a another one the ZS values or down 10% so if it passed last year it could be a C2 this year.

You already said that lol

No more like 5% due to Cmin factor

Surely new circuits have to be rcd protected

Exactly, and the moon is made of cheese!

Well every body knows that.
