External Consumer Unit

[RickyB1990]

Good morning guys

Was looking for advice with regards to installing an outdoor consumer unit. Customer is looking for power to be installed from there property to an area in there garden. There installing a future hot tub and summer house and any future lighting and power. They currently have a small log cabin where I was going to situate a 4 or 6 way consumer unit which can feed any future points. My question is would it be best to fit a standard 18th edition metallic board inside a ip Rated cabinet? I've seen online there are ip65 consumer units which are plastic but obviously that wouldn't meet current regs. I'm just wondering if there is any other things to take into consideration with regards to temperatures

Any advice would be appreciated

Fair enough on the point of Ze but it still applies that your measurements will increase at the new db effecting trip times.

Yes measurements will increase, but that does not mean there is any problem, if everything is designed correctly the increased values will still be compliant.

Also if you live further from the DNO’s step down transformer the Ze will also increase before you have even thought about extending the earthing arrangement. So should also check a previous EICR for the Ze reading at the main head.

Personally, I would take a Ze measurement myself rather than rely on someone else's maybe drive by scrap of paper.
