PART DIY HOME 32A CHARGER INSTALLATION

Has anyone with sound DIY electrical skills install their own 32A 7Kwh Home Charger? ( perhaps a basic charger)
I look at installing a home charger as just another power tool device plugged into the power supply but this requries
specialised handling at the supply end.

Say, run a 32A+ cable from the consumer unit to the Charger location ( this is not difficult but is where it can take electrician much time and effort )
and Install & connect the charger unit outside the house.

Then engage a certified electrician to connect the cable to the Consumer Unit correctly and test.

Re: PART DIY HOME 32A CHARGER INSTALLATION

I Installed mine in my garage myself - had the main house panel there. Followed this video:

A few who have installed outside the garage have just run the conduit through the wall and into a weatherproof box that the charger plugs into. I just ran the conduit to a plug receptacle I installed inside right next to the garage door - I normally plug the car in, inside the garage, but can run the charger cable under the garage door and plug in outside if needed..

Re: PART DIY HOME 32A CHARGER INSTALLATION

The box is just an outdoor electrical junction box - like this one on Amazon. Look below this listing on the page for more. https://www.amazon.com/dp/B09DVNZHPD/re ... s9dHJ1ZQ==

The guy just cut out a slot in the bottom, then lined the edges with electrical tape, for the charge cord to fit through.

The wiring comes out the wall and through the back of the box, into the back/side of the small plug box installed there to plug in the charger.

Re: PART DIY HOME 32A CHARGER INSTALLATION

I would put some protection on the "charger" cable where it goes out of the box on the notch in the metal. Some duck tape, or a rubber grommet ( cut to be able to slide it on the cable)

Or fixing the outside part of the cable to the wall with a shock cord

One day, someone will pull on that cable, and it will damage the rubber of the cable at the notch. It is just a question of time before it happens on such a setup.

I'd also suggest to make sure all high-voltage wiring is terminated with ferrules:

In the USA not in use. All residential and commercial wiring is single core, not multi-strand.
