New meter connection, new CU… planning for PV: What grid isolation switch is needed where?

Ran the 3 core 25 sq today from meter box to where the cu will be. 16 meters of cable weighed 23 kg so not easy to handle.

Step 1

Modify a cable spool

Step 2: separate the above and drop in the coil

and mount on a pipe above the duct: hole in cable roll reduced to 60 mm

Weight of cable working with you as it is pulled off the roll and pushed into the duct.

Used Blue gel lubricant to make it easier, worked well.

Step 3: finished job: used plastic covered braided wire to pull as the hole in th meter box was too small for the 8mm blue twin loop

Thanks Will check that out: it was difficult to pull through but should move now.

Edit: checked it out: moves very easily back to the CU location

Thanks for contributing.

Can you say a bit more about the rationale behind the question.

Probably not as it will be a ground based system as I suspect the DC cabling would be very onerous.

At this stage just want to plan for ducting and any additions to the new CU
