If I encountered this on an EICR I’d still code it as a C3. It is technically compliant, however the Zs exceeding the MCB type and rating is just bad design.
Having said that I’ve rectified many a C2 for high Zs by changing to an RCBO.
Would the loads allow for a reduction to a C20?
I’m with you on that, protect with an RCD. Gives Fault protection as well and additional protection and ensures it will disconnect up to 1667ohms.
I’d also write in your EICR that you recommend more frequent inspection interval on the floodlighting as the fault protection is relying on the...
In Theory that’s a good argument but if you will be adding or moving switches or sockets or adding lights you’ll more than likely end up needing a warrant...
You’ll need a building warrant if you’re planning to rewire a flat in Scotland. That could be very tricky if you don’t have Scottish/UK qualifications.
Beware of derating the current carrying capacity of cables when putting them in conduit or trunking, you may find that they are already...
Spot on The Requirements of sections 1-6 must be complied with in a special location unless its otherwise stated in that part of section 7 that a specific requirement of section 1-6 is not applicable.
In basic terms you could say that Section 7 contains additional requirements or...
I reckon you could @Dan I think the best way to record the additional inspections would be an inspection checklist similar to that as found in an EICR but one for each Section 7 location.
When doing an EICR on something like a swimming pool there is a section on the inspection checklist which asks about any other special locations and asks to record the results of the inspection separately. My question is are there any templates for inspections for special locations (especially...
So he didn’t remove the tails? But wiggled them?
Sounds more likely that there’s been a problem hiding there for a while either from a loose connection causing the cable to overheat and eventually melt into the clamp or the wiggle has exacerbated a defect already there and with a little load on...
Certainly not a standard thing to do on an inspection.
When you do the 2391 (inspection and testing) you are told to disturb as little connections as possible to ensure you don’t create faults.
It’s highly unlikely that the electrician would have removed the tails and reterminated them on an...
Still not done properly though, pretty bad practice earthing the armour from the far end of the circuit.
Zs of the braid would be significantly higher.
And installed contrary to manufacturer’s instructions.
Things wrong in this picture;
1. Basic insulation showing (meter cabs are not considered suitable enclosures) interestingly site applied insulation (heat shrink) is no longer classed as suitable in an application like this either.
2. Black being used as the N (personally don’t see a problem...
