Chargemaster Charge installation part 1

Standard

Well today was meant to be the day that Chargemaster installed my 32amp type-2 socketed charger in my garage. However as with all the best laid plans it didn’t happen. It turns out not only is my consumer unit (fusebox to the rest of us) in a awkward place, but it also has no spare ports. Therefore I will require an electrician to come and install a second consumer unit so that the Chargemaster guy can come back and run a big fat cable (32amp) from this new consumer unit to the garage (quite a long way away) and put the charger on the wall there. The Chargemaster guy could not do this as he is not allowed to pull the main fuse (big black thing below the meter) you have to be an electrician or power distributor to do this, and the previous installer did not fit a circuit breaker to isolate the wires to the consumer unit so that they can be split to feed a second one.

This throws up another quandary in that the wiring in my garage (not done by me of course… I’ve only been here for 6 months) is not exactly up to building regulations. So I could ask the electrician to run a really big cable (60amps or thereabouts) from my meter to the garage where it would terminate at a newly installed garage fusebox. Then rewire the garage sockets with a proper ring main, and then connect the charger to this new box.

So as with many similar things the “free” charger will not turn out to be entirely free. I might end up with a much better wired garage for my time and money however, and this is no bad thing, but I’ve been successfully charging the car using the supplied EVSE via a regular three pin plug for the last two months and have had no issues – no RCD tripped, no fuse blew, no cable heated up, nothing caught fire. I suspect electrical safety regulations regarding ring mains (or lack of them), cable sizes and spurs are, in the UK (or perhaps Europe) at least, a little overly-cautious.

More on this problem with some eye-relieving pictures of electrical things, to follow.

    Would that also mean that they cannot then change the MCB in Consumer Unit? Looks like my garage MCB is only 6A and would probably need 40A to be installed for type2 socket charger.

    • Two questions here: Can the charger installer isolate the necessary cabling to add a 30 amp 6mm2 armoured cable from your master consumer unit (or secondary consumer unit if the cabling between them is sufficient)? In my case there were no spare ports on my master consumer unit, so in order to add a second one, the installer would have had to open a junction box between the meter and the consumer unit, the only way to isolate it would be to pull the master 80a fuse, which he is not qualified/insured/permitted to do. So I had to get an actual electrician to do this, technically they shouldn’t do it either as it is the property of the electricity distributor, but they do by gentleman’s agreement with the distributor who aren’t going to turn up to remove a fuse, sit around smoking a fag for an hour then put the fuse back and crimp a seal onto it. As for your garage MCB then no 6A isn’t going to cut it. The site survey for the charger is free and if they can install then they will if not they’ll come back once you had the work needed done.
