Thanks for the quick reply. I am not really bothered as long as it is smaller than 8" high. I want to fit it on the side of my steps on the white bit.
The house is a very old grade 2 listed terrace so otherwise I would have to install it on the front of the house which would look ugly and I might get in trouble from the council for putting it on a listed building! If I get away with the council it wouldn't matter as the wife would kill me anyway. lol
From the spec sheet for the Chargemaster / Polar unit.
If you place the connector back into its holder, it does protrude quite a way out thus increasing the depth. However you can just leave it wound around the charger body ad there is no real need to place it in the holder.
AFAIK You will not be able to install a dedicated charging using that close to the ground according to the guy that installed ours. I don't know the regs myself but he said that it had to be a certain distance above the ground or he couldn't install.
As I say, I don't know the details but I would check it out with an electrician first before even installing a 13A that low down
There is a chance that my installer was just talking rubbish but he was quite certain because when he asked me where I wanted it he commented anywhere was fine on that wall as long as it was above xxxxx above the ground "because of the regulations"! I can't remember the xxxxx as I wanted it about chest high so it didn't really apply so I didn't take much notice.
The height limit has been decided for two reasons:
1. Accessibility for disabled.
2. To avoid damage by vehicles.
My understanding is that they are part of a code, i.e. not an enforceable regulation or law. simply ask the installer to cite the reference. This will give you ammunition to defend your decision e.g. putting a couple of protection posts in front to avoid damage or having the ability to put the plug holster higher (on one of the protection posts?) should higher accessibility be required in the future.
The IET Code of Practice for Electric Vehicle Charging Equipment Installation states that:
"The electric vehicle charging equipment shall be installed such that the main operating controls and any socket-outlets are between 0.75m and 1.2m above the ground. This is to ensure their accessibility by both able-bodied and disabled users, based on recommendations in the British Standard on the design of buildings, BS 8300:2009 + A1:2010."
Speaking as an installer, I have installed chargers in domestic properties which are outside of this remit, I always make people aware but sometimes it is impossible to install it at the required height. Unfortunately, none of the chargers i'm aware of would fit in the space indicated, sorry.
It would be possible but I don't think it will be the most aesthetically pleasing of things! I agree with AndyG, a timber post will probably be the best bet. We have used 100x100 gate posts to install chargers on before. They look nice and neat and are cheap. You'd just need to dig a hole first though.
