EV charger installer

Yeah ^^^.

 

Charger installation needs a specialist to ensure it's safe under all circumstances. It really does need someone who knows what they're doing.

 

Also, most (all) won't install on a 15/45, they want a 30/100 or a dedicated 15/45 (which can be TOU for even lower costs).

 

EDIT The home charger installation instructions for a GWM (Great Wall Motors) charger, Thai of course. Installing to those requirements should be good to go for most chargers.

 

Note - I would go for a Type-B RCD rather than the specified Type-A.

I got an MG EP new nearly 2 years ago now; at that time the 7.5kw charger was included free, and installation was included as well.   I live in a condo and the juristic office said we couldn't install there, so we tried at my girlfriend's house in Rayong.  ~10 year old large house in very nice neighborhood.  The installers arrived and said that all new lines would have to be run direct from the utility pole.  They didn't think the existing lines could handle the additional load.  This charger requires a 40amp circuit (draws about 32 amps when charging).  I wish I was there to get the whole conversation as g/f doesn't know much about it and it's possible they were being lazy and just didn't want to do the job.

I ended up having an electrical contractor at the factory where I work in Rayong install it in my work parking spot; cost 1500 baht including the meter.  To be noted, the line was already run to the parking area, so just a bit of wire, breaker, ground, and a mount were needed.  Doubt he'd travel far from here to a job, but never know.  Where are you located, OP?

 

As a side note, this same guy fell off a 8m high work platform and broke his hip about 1.5 years ago.  Amazing he didn't die.  Was not harnessed or tethered.  So not sure how much I'd trust his work at my own property.  The install at work is legit, though, complete with a proper grounding rod right below the charger.

I think the important part is that "it works" is not good enough.

The cables and breakers must survive any bad condition which could possibly happen. And with so much power the risk of a fire with improper installation is not low. Be careful!

We got an MG plug-hybrid thing too recently and again yes (I'm not there my wife is handling it) we seem to have one charge (sorry no pun intended ???? ) after another to get it all up and running, like additional power to the house. I think it's all done now I'll check it when I get there (not that I'm an expert).

 

Certainly wasn't cheap but as pointed out  "cheap" can also mean "dangerous".

Simply contact the local vehicle brand distributor and ask who they contract their installations with.   Surely they/contractor won't mind an extra side job.

 

Have it done by experienced pro, knowing that unit.

There’s a huge difference between a “proper grounding rod” and an earthing ground rod that works. 
Ground rods are notoriously difficult to get to work correctly and unless he had the proper test equipment to confirm it’s working correctly, then I very much doubt it’s working correctly.

What surprises me the most is that here we are in 2023 and you’re installing an EV Box that requires a Earth rod. All EV wall boxes here in UK are now required to have built in protective systems which negate the use of an earth rod. 
Thats Thailand for you, years behind the first world countries electrical regulations. ????
