I would argue that it’s current method of installation is less than ideal, given that the only form of protection on it will be a fuse somewhere between 200 and 400amps at the local substation, which will possibly not blow if that cable were to be damaged. If nothing else they may come out and...

No what I meant was they switch off the mains before switching on the generator so a short interruption. Rather than synchronising the generator and the mains and then switching off the mains, so no interruptions

This is a link point, the fuse carriers are where two circuits meet, fuses can be inserted or links to ‘back feed’ one circuit and the fuses removed at the transformer end Obviously in this case the two transformers serving each circuit were affected by the outage so they had to use a...

Makes sense. So does the three phase rcd/single phase generator have any bearing on it?

It took me while but I presumed he meant turned the switch on and held in the test button (unless as it’s an active RCD this one has a ‘start’ button like a motor starter) I basically took it as the RCD only stayed in while it was manually made to stay in Something like this?

Does the issue have to do with it being a single phase generator and the socket being 3 phase? If so, have all the phases been connected to one phase via some sort of lead? Or some other shenanigans going on? Failing that are they only trying to power up one phase? My guesses would be that...

Ah sorry maybe i misunderstood, am I to take it this is not a grid connected system? In which case yes, just cover yourself regarding the security of the panels and suitability of the roof to take the additional weight (plus allowances for wind loading) otherwise crack on

There is actually very little preventing you from doing a self install, but a few things to consider - you will need an electrical certificate and part p notification for the electrical side -from experience most insurers only want to know you’ve had it fitted, they aren’t too concerned who...

Quick, run a cable back up to the house!

Definitely an oil injection point On the phase layout, a lot of smaller electricity undertakings used odd phase rotations pre nationalisation and so when the national grid was formed they did keep the old phasing as was.

Agreed. However without a reference the generator ‘earth’ will be just floating, potentially resulting in a voltage existing between the generator (which I would think has a metal frame) and the ground. Every generator I have ever worked on, okay typically bigger (50-500kva) has an earth...

So I’m not going mad then. I thought I had a point!

Cable fault, overhead line down, not saying every time but if there’s a power cut there is a usually a reason for it

Care to elaborate?

What is the earthing arrangement in the house? Unless it’s TT you cannot use the DNO earth for your generator, as if there is a power cut, there is a good chance there probably won’t be an earth. Also best practice to have it completely separated from the mains, so no risk of backfeeding the...
