rewirable fuses

[dcelectrical]

evening all - I have a question for some of the more learned members, I am currently trying to make a landlord understand that her rewirable fuseboard isn't up to date, so I know that in 1991 the 16th was launched meaning it wasn't to regs but I was wondering if there was any requirements in the 15th for MCB or if it just stopped being compliant in the 90's. doesn't really matter as she missed the change in regs by 25 years anyhow but it just made me wonder.
Thanks in advance for all the comments!:wink_smile:

Just because it has rewirable fuses, it doesn't mean that it needs updating. Like netblindpaul says above the circuit breakers just need to be considered in the design. Albeit when I come across such a board, I would recommend an upgrade as there are newer, circuit breakers available that should trip in a shorter period and ease of maintenance would be another reason to upgrade.

2015 even!

having been out to properties where sinks have potential and giving a little discharge every time the tenant washes up I like to test their potential especially when I am called into a tenant complaining of minor shocks from the cooker.

extension leads under the sink are perfectly fine, especially in managed properties where 3 or 4 tenants live and will regularly put every appliance on in the morning when getting ready for work.

with regard to carrying out inspections I just write down whatever and recommend the landlord get a quote from some new English people to do a budget rewire and charge £400 quid for the privilege

If there is a potential between the sink and electrical earth then there is a fault in the installation. Bonding the sink will not fix the fault, only disguise it whilst causing a current to flow through the bonding conductor due to the potential difference and causing the sink to get warm due to the energy dissipated by the flow of current.

Yep ok, fair do, I was working last night on some pre A2 stuff, so I had that stuck in my head, back on A3 today!

I still think I could design an install to comply with A3 and use 3036's.

You definitely can, be expensive though.

 

[netblindpaul]

No one mentioned cost!

Could you clarify the last paragraph - I'm not sure what you mean here? Cheers. Daz

I could do it cheaply, but it would look a right dog's dinner.

The sink isnt earthed supplimentary bond in a bathroom the good idea but there is no requirment to bond a kitchen sink , the olny time i would code a good condition bs3036 board is if the fuse cover was missing

Oh dear. Do you really know enough to carry out an EICR??

Why would you "earth" a sink? A decade or so ago one had to cross bond the H&C pipes in a kitchen, but that was removed several editions ago.

What is wrong with the extension leads? the load is limited to 13A in the plug. Not the best way of distributing a load, I would agree, but they are not part of the fixed wiring.
Some advice should be given if they were powering a washing machine and tumble dryer perhaps.

Note that since Amendment 1, BS7671:2008 non-compliances with the requirements of the current edition of BS7671, that do not give rise to danger or NEED improvement, do not require reporting in an EICR.

yep like that , pics on page 7,9,14 of the electrical safety first booklet are one's I took, just how we found it the cable was VIR

...causing the sink to get warm due to the energy dissipated by the flow of current.

Sounds like a nifty way of keeping your bath water warm during a long soak.

swap them for pluggable wylex mcb`s, cheap on ebay. i have a collection scrapped on various jobs...
you can add an rcd upfront if the installation tests ok.
