Are you adding 10 New circuits? Have yo calculated the new load?

Hi John. All good here thank yo. Hope all is well with you and yours. I meant the logic of the thread. I fit 5 sockets and there is a trip due to the equipment used. I don't see how I would be expected to sort this at my expense. I just wonder if Eric thinks I should replace a socket if the...

Are you running new circuits, or taking feeds from your exiting circuits? New circuits would nit normally require a JB. If taking a feed, how come you have the socket and light circuits with a JB at the same place in the circuit

Does this logic apply if a customer plugs in an adapter and overloads the socket, or trips over an extension lead?

This thread starts with `here is my solution, could you advise how to do it` I would ask why you need a second CU and what circuits will be fed from it?

I second crystal ball. You get really interesting work RF and show real skill.

The point is that you cannot issue a Electrical Installation Certificate if any of the circuits have faults. I'm not really sure I understand what you are trying to get across here. As I see things, there are 3 options for quoting. All work fine, when no faults are found. 1 - Quote 1 day to...

The tests are carried out to confirm the circuit is safe, not that it is a ring. FYI, it may be on a radial. Why not mention safe isolation and locking off the circuit, as that is something we do. We all remember BAS, who listed a set of books to read before anybody tried any diy electrical...

If an EICR finds a fault, the option is to fix the fault or advise that the CU can't be changed.

I have a number of points to make here. 1 - If a customer is having a CU change, the installation must be tested and any serious faults rectified before the CU can be handed over to be used by the customer. An upfront inspection gives time to address faults in a planned manner. 2 - A piece of...

The advice above is all good. I walk away from cu changes if the customer refuses an EICR as the first step. It is more convenient to get any faults fixed between an inspection and a CU change than it is to get them fixed while you have now working CU.

You don’t need a socket in the corner to make it a zone.

I don't think you need an angle. I don't have a drawing app, but you could chase into the corner. Continue for a couple of centimetres before drilling straight through. Chase from the hole to create the zone in the second room. I've done this when there is a concrete floor. I suppose Winston...

Yes they do when you have fittings on both walls and they are in line.

I’m talking specifically about installing a 37kw oven on a RFC and overloading the fuse in the plug. In this case we would not apply diversity to drop the load below 13amps.

If the oven is rated at 3.7KW @240v, it is over the limit for a 13amp fuse and should be on a dedicated circuit. Even converting the power rating to the value at 230V only drops the load by a small amount. We don’t apply diversity when determining the breaker on a single circuit. We apply...

Hi chivers. I saw this on my phone and missed the 3 core. Magnified image and can see where you are coming from. Its not suited to quickwire.

They only make a connector to replace a ceiling rose (and the jb in the photo is acting as a rose) with loop in and out, switch and load. They are expensive and I've not really looked at using them in a 2 way circuit. One to think about. There was a post that they were working on a 32A version.

For jobs like this I recommend quickwire connectors. So simple and quick to install and easy to fix to the structure.

I think you mean 32 as opposed to 230 in your calcs. Also at 46.4A the breaker should not trip within an hour.
