Discuss 2.5mm 2-core SWA for EV point? in the UK Electrical Forum area at ElectriciansForums.net
As the charging point must be outside the DB equipotential zone (separate earthing rod), are people using 2-core SWA for EV points and eathing via the armour?
Thats a very sweeping statement ........ what makes you think that?

Most chargers are either 16 or 32 amp but the protective device inside is usually a rcbo and rated at 20 or 40 amp and usually a type c.
You then have to consider voltage drop, i installed one on a 10mm 2 core swa circuit and them put a rod in. Same charger on anothet circuit was 6mm H07 but used PME as it was only being used within the waeehouse and not outside.
Every install is different.
It all comes down to circuit design. Use the formulae in the regs or osg and you will find the answers.
I made this statement, because I've yet to see a TT'ed EV system!
Were they in complance with the 70V reg or just connected via cpc to the installation earthing block?
