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?

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

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.

What you on about ?

I know what they are, its the principle of being told duff info regards 3036 fuses

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. £££££!!!!!

Some of these inspectors are self employed , and float from one scam to the other I had noticed on some paperwork once ...

[Pondy]

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.

Surely new circuits have to be rcd protected

Really?

 

[ImpededLoop]

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.

 

[telectrix]

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.
