All you know for certain, from that description, is you have either a fault current or overload condition. Other than that, you are just guessing until you get there.
You would do an EIC as it is a new circuit. You would just put the circuit that you have installed on it.
If main protective bonding was required, You would need to ensure it was satisfactory.
I'd have to agree with Ian on this. The circuit does not meet ADS due to very high impedance, however it would require a fault to present an immediate danger. C2 for me.
You would seem ideal for the NVQ3 2356. That would get you a jib gold card.

RCD'S are tested in relation to thier function e.g. 30mA RCDs providing additional protection tested at 5x (0 &180 deg) and highest value recorded.
RCD'S rated 100mA or higher used to provide fault protection or fire protection, tested at 1x (0&180deg) and highest value recorded.
Yeah, off top of my head, SPD's, AFDD'S and some slight changes with regarding RCD'S for socket <32A. We are supposed to demonstrate we are working to 18th even without the qual. Doubt he will grill you too much on it but show him you have made some effort and tel him you have course booked in...
Are you good and effective at fault finding and rectification? Before you knock it on the head, try some national facilities firms. Lots of opportunities and interesting work.
Most HMO's go gas central heating and indirect unvented cylinder. Put as much on gas as poss to reduce electrical load. From a design current point of view, a 6A lighting allowance would be more than adequate for whole building but would be spread over circuits to reduce the disruption from a...
100% is upstream of Meter as already said so it's the DNO issue to resolve. Could be line or neutral but frankly who cares at this stage......call the DNO and report it.
Awesome video OP :)
What electric hobs are you proposing?
What are you doing for heating and hot water in the building?
3A lighting per room? Are they having floodlights?
15A ring?
Dave meant the stat switching into the contactor coil will be in series with the integrated stats in the heaters.
I understand what you are suggesting too.....having 2 stats in parallel controlling the coil so that if either closes then it will bring on the heaters (if internal stats are...
Amazon have sold loads of these that peeps can't use.
They could make more money selling the "old house loop in/out kit"
They could charge say....30 quid for some wagos and a metre of singles so they can have it hanging it out of the ceiling light fitting by its wires. That would look mint haha
I know you are referring to the the DNO 3M max rule. His DP switch will be within 3M of Meter, SWA CCC is ok and he will likely still acheive ADS (will need to verify) protected by cut out fuse.
Is there a specific rule prohibiting that and stating you must fuse down?
Earth the steel armour of that cable and fit your DP isolator.
As you have TN-S arrangement, need to check what is your Ze and what rating the cut out fuse is. Install method of SWA doesn't appear to need a derating applied so can likely avoid fusing down.
With yours, You can go up to 0.42...
