    Service Head scenario

    Hi, I'm a trainee electrician and am thinking about upgrading a consumer unit. I'm aware that anything south of the CCU belongs to the electricity supplier and that we're required to call them out to remove the fuse from the service head before starting such a job; but I'm curious about this...

    bs 1361 fuses service head

    o.k. bs 1361 fuses have earth fault loop impedance times as follows 80A-0.40ohms 100A-0.29ohms (yes based on 80% values, 5 secs distribution) In a TNS you can goto a max 0.8ohms Ze so even if you use the smallest rated fuse in your service head, 60A still max only 0.56ohms and your Ze was...

    Service head query

    Attached is a picture of the service head at our house. Is this a type that the DNO should replace for free upon notification? It looks very old, and may have a fused neutral line, I can't quite see through the sight glass to see whether this is the case. The conductors going to the meter look...

    Service Head

    I don't think I've seen a service head like this before, I've only got the picture to go on at the moment and it's not that clear. I can't see a fuse anyway. I'm assuming that what I can see in the picture is a cover that either opens or comes off and presumably has, or should have, a seal on...

    Supplier service head and cut out fuse needs replacing?

    Hi all I completed my first EICR a couple of days ago and some of you have helped with the codes, a major concern I had was the age and condition of the service supply head. As you can see from the photos the wiring looks 30+years old with a tangle of wires going everywhere. Do I call out SSE to...

    I want to upgrade the main protective bonding conductors on the gas/water from 6.0mm to 10mm.

    Who's responsibility to provide earth to main service head on TNS

    As a maintenance electrician i've been given jobs to replace stolen earth bonding from intake cupboards in various blocks of flats. Some are PME and some are TNS. Obviously for PME i can provide earth to the Neutral via the bolt on the side of the service head, but on the TNS where the earth...
