Good Or Bad Advice (Re-Wire)?

it's re-wireable fuses

Sounds very suspect to me. It isn't resistance that trips circuit breakers or blows fuses, it's the amount of current flowing through them. Low resistance in your wiring is good. Conversely, if increased resistance in the circuit caused circuit breakers to blow, then how do we manage to use devices like electric resistance heaters successfully on these circuits? It's not like the breaker knows if the resistance is in the wiring or the appliance. All appliances are effectively resistors that only allow the correct amount of current to flow through them in normal use. Besides, the only thing breaker detect is current and blow when too much passes through them, because that indicates one of your appliances has failed or the wiring has become damaged, and ironically greater resistance decreases current so I don't see it encouraging this at all.

Im guessing he was talking about the resistance of the insulation rather than the conductor.

Third electrician concurred with the second - i.e. that re-wire was not even on his radar.

So, looks like I was nearly conned!

Thanks guys for all your advice.

The second electrician is coming on Friday to do the work. He said that if he fits the CU and finds any minor faults that cause it to trip he will sort them for free (i.e. poorly wired light switches or whatever). Anything major is a different matter.

We'll see!

I go away for 3 weeks the day after he does the job, so I wont know until then anyway, but I'll feel safer knowing I have a modern CU with RCD fitted.

Dont forget to ask about whether a a certificate will be provided for the work before the work starts (if you haven't already)

A google of 27b/6 doesnt bring anything up?

He did mention that he'd have to make sure it was all in order before he left as he'd have to make a certificate with his name on it and submit it somewhere - I assume this is the "part p" certificate people talk about?

I am now having cold feet AGAIN - thinking the fuse box we have has been faultless for 28 years - should I not just leave it alone.

I am worried that a new RCD box will just cause more problems - finding tiny faults and tripping constantly etc leading to more (expensive) work.

As things stand, it all works perfectly!

It may work, but it may have hidden issues

I find that 10% of consumer unit changes have faults that involve removing / repairing wiring.

It can't be that bad as 2 electricians have not condemned it upon looking at it

I find that problems arise in kitchens and bathrooms where kitchen firms have 'all in one' tradesmen
