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?

 

[armbands0]

Can you still buy new 3036 fuse boards?

 

[davesparks]

You can still buy Wylex standard range boards with either HRC fuses or MCBs, I don't think you can get rewireables new any more though.

 

[armbands0]

Sorry did not read it proper, existing circuit alteration?

 

[armbands0]

disconnection time depends on the max Zs value, the lower the Zs the quicker it will rupture, even for a 3036

 

[HappyHippyDad]

Sorry, I may have worded it incorrectly..

I dont mean to put in a new BS3036 board. I simply mean to carry out work in a household that has a BS3036.

He has stated that if you want to add a new circuit to the electrical installation in a house which is protected by BS3036 rewireable fuses then this would be unsafe as they do not meet the 0.4s disconnection times. he has said that you would need to change the board.

In fact he said all BS3036 boards should be change as they are dangerous and do not meet the 0.4s disconnection times

 

[HappyHippyDad]

disconnection time depends on the max Zs value, the lower the Zs the quicker it will rupture, even for a 3036

Thats what I said! He disagreed! He didn't explain why he disagreed.

that assessaor will be a delight to the Electrical Trainee's who want to recoup their £6000+ asap. " that's board's illegal, mrs. pensioner i'll have to replace it for £500".

 

[amlu]

swap 3036 for plug-in mcb, same fitting. job done.
get them off ebay, i have a box full scrapped on the jobs.

I would go as far as advising that they move out until the work is carried out for safety reasons ...

 

[Octopus]

Was the assessor ex NICEIC?

I often do that, gets them out the way. Also makes the job sound more important and can charge more. £££££!!!!!

Surely new circuits have to be rcd protected

 

[telectrix]

Surely new circuits have to be rcd protected

only if they need RCD in accordance with BS7671.

Really?

Really?

You only need six characters to post a reply so you wasted one there.

Seriously though, please offer up advice or opinion rather than one line answers.

looked more like 1 word to me. this is 1 line. :ack2:

ok..

 

[HappyHippyDad]

Ok... so does anyone have any idea if what he is saying is correct?

Is it ok to connect up a new circuit to a BS3036? This is in relation to the 0.4s disconnection times, i.e the assessor says it does not meet them?

My answer was that it depends on the Zs as to whether the BS3036 would disconnect in time, but the assessor did not accept this.

 

[telectrix]

then he's a clown.

They still disconnect the same as they always did!

 

[ImpededLoop]

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.

 

[R G]

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.

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

 

[polo1]

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.

 

[test electrical]

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.

 

[test electrical]

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.

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?

 

[HappyHippyDad]

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

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.

No more like 5% due to Cmin factor

It should be called the Vmin and were did the 0.95 value come out of EU again vote UKIP

 

[telectrix]

a recent poll of around 11,000 ppl came back with 80% saying get out.

 

[trev]

Anyway, back in the real world.
Steve, ask him to come on here and post his opinions so we can debate the issue.

 

[telectrix]

how can it be a C2? been safe for 20 years. where's the potential danger?

 

[test electrical]

telectrix I was talking in general with this new amendment Cmin 230vX0.95 218.5volts this is the voltage you have to calculate your ZS from now my old man is right the older u get the more bull u get. Roll on 85 and don't let the chips get u down.
