So the House we are looking to buy supposedly had a new CU fitted in 2017 and as much as I took a look at it when we viewed it I don't remember much about it other than it was metal cased and shine white!
The Solicitor obviously asked for installation Cert as it was done so recently but this hasn't been forthcoming as its a probate sale and the person selling it probably has no idea when the paperwork for it is. However what I have just received is is a fresh Electrical Installation Condition report done last week.
I have a few Q's about it.
I don't remember seeing a RCD at the end of the row of MCB's so i assumed it didn't have them. The Report lists each circuit as being protected by 61009 type B's. Am I right in thinking these are RCBO's?
On the Observations section most stuff is pretty self explanatory and easy to fix like no water and gas bonding, no RCD protection on the garage supply which given it also was listed that the garage supply is pretty rubbish and could do with retiring isn't a surprise.
Edit - The Garage not being RCD protected but has a 60898 type b which looks like a normal MCB. Is there any reason why I couldn't just swap it out for a RCBO like the other ones? Or would it be better to rewire the garage as its knackered anyway fitting a separate RCD protected CU in the garage?
It also mentioned the Main Earth Terminal supply is only 10mm and should be 16mm. Is this something you'd expect to find on many older houses and it's just the regs have changed to make it a larger cable now?
Lastly one of the Circuits(upstairs sockets I think) had a higher than expected Rn reading(1.61) and lists potential loose connection socket point leading to potential for circuit overloading. The house is in dire need to fairly significant remodelling anyway so i'd be surprised if every single socket face didn't come off the wall at some point and the connections will be checked. Am I right in thinking this test is nothing more than a basic continuity test end to end?
I do have a fairly healthy knowledge of electricity as I fix signalling for London Underground (plus access to decent test equipment) and did very basic ring mains and lighting circuits as part of my apprenticeship but the finer details of Home electrics are going to require more studying and asking questions on here for as long as you're all so kind as to answer my rambling!
Many thanks
