Hi all, new around here so go easy please
Got a situation where I can’t get a definite answer.
I currently have an old 7kw 30A Chargemaster, which I want to replace with a new Easee One 7.4Kw 32A charger.
The way my install is, the consumer unit is under my stairs in the middle of the house, and 6mm twin and earth (2x6 +2.5) was used and all signed off, and tbh, have never had any issues.
The cable is chased into the wall slightly, then drops under the floor and is clipped along, to the front of the house, where it then is chased up the wall slightly, and out into a junction box.
From the Junction box, I’m assuming they have used SWA cable for that short run upto the charger.
I want to get my electrician to replace the unit, which he said would be an easy swap, as the cable is capable of carrying 47A and there is minimal loss as the cable is not insulted in walls or conduit.
He did say he would change the MCB to a 40A as the current 32A would not be sufficient enough.
Now just to check and be sure, I’ve spoke to a few other EV installers, who some agree with what my electrician is saying, but then others are saying that the earth has to be the same size cross section as the twin wires?
I clearly don’t have this, as it’s 2x6mm + 2.5mm.
Some saying I need to rewire, which I’m trying to avoid, and others saying, that I’ll be totally fine with the current cable.
I’ve been told SWA etc is not necessary as none is exposed or buried underground but is clipped under the floor.
My current charger is a “dumb” one, so am replacing with a smart one.
The Easee One, has built in RCD and PEN and has its own built in power monitoring without the need for extra wires back to the consumer unit.
Can someone please help shed some light please.
I’m also in the UK if that helps.
TIA
