Low voltage can cause higher current, if this is only one phase it can affect the frequency. This is protected at all costs

I had issues with this at my workshop - incoming was low 218v at times. When fitting EV chargers for working on customers cars
they can change the voltage at substations on the transformers by altering the tap changers on the secondary supply and other methods depending on the demand a farm i worked on out in the sticks dropped to under 200 at teatime in winter when it was milking time and everyone making grub and couldnt pull the motors over to start

Mate of mine had the same charger fitted and weighed out for EV Ultra cable 
He's having external wall insulation fitted. First off then spacing it off on timber like that is a bodge and a cold bridge, should have used thermally broken standoffs and insulated behind. Then the cables coming in from below are just fugly! Such a shame when rear cable entry is an option on these. It's why I insisted on mine. The installers will generally want to take the easiest route.
His:
Mine:
For the Cat-6, run in 20mm flexible conduit, I had to get creative with the IP rated stuffing gland and some CT1 rather than use the normal folding/snap together ones you get for it. I later changed the SWA gland for a Storm / Shield gland, can't remember which.
Mate's wishing he'd insisted on the cable coming in the back and that he'd known about thermally broken standoffs I think.
FB marketplace is often a great place to pick up part rolls of cable. Though I already had the 16 & 10mm² SWA here already (my hoarding tendencies paying off), I got a part roll of duct grade Cat-6 on FB for peanuts from a guy who'd also just had a charger fitted.
As an aside I'd had my 10mm² SWA so long it was old core colours, red, yellow, blue & black. I just sleeved the ends in new colour heat shrink. All tested fine.
