It does but only if its used between two Tesla wall chargers. They share a set amount of amps between them.

Oh cool, then it should be fine to use a second Tesla wall charger

Will they split the charging current or does one get priority?

Thanks for the replies, yes, two Tesla chargers can load share, but will be about 3.5 KW from each when running together. So that's why I am thinking of just a 16A commando plug, also give me about 3.5 KW and I can use it for other uses as needed. And much cheaper.

Some way that the Tesla charger and 16A commando could load share would be much the simplest for me. Don't particularly want to limit my Tesla charger to 16A all the time though.

Otherwise I would have to decide between two Tesla chargers or a 16A (or even 32A if sparks happy with that) commando connected back to the fuseboard

The downside of having a commando socket is that you cant auto load share with the Tesla wall connector then and will have to manage it manually.

Much handier to come home with both cars and plug both of them in knowing that its safe to do so and both will be charged by morning without you having to do or think about anything.

It is more expensive alright though to get two charge points so thats a personal decision for you. The convenience would justify it for me particularly since its a long term thing, not just something for a few years.

At a push, the present Tesla charger could be set to 16A (or 20A as the fuse breaker is 40A I think, will double check).

Need to think about it and will talk to the charger installer I used before tomorrow too. I like the idea of a commando plug outside for other temporary uses possibly (like Christmas lights).

Finances not an issue really unless choosing between rough equivalents

Do the Tesla chargers monitor the current load on the circuit using a separate CT clamp? If that's the case then you can have it both ways and fit both an outdoor socket and a second charger

If they just use internal current monitors then the above probably won't work because they won't know when the outdoor socket is being used

If you have the money, I'd go for a second charger, it's more convenient and when one car finishes charging the other will have the full 7kW available

If you’re buying a second Tesla charger I have a brand new one never unpacked out of the box. Bought in October but installed a Zappi. Could do you a good price on it.

Instructions describe a terminal block, nothing about CT clamp. Hopefully the charger installers will have more answers tomorrow

Will DM you, thanks

Watching a vid on youtube recently, an electrician there shows the jobs he does, fits lots of chargers. Recently replaced his own Zappi with a Tesla.(He uses tesla as his work vehicle) Within 24 hours he went back to zappi. Not happy with the safety of the Tesla charger, compared to zappi.
I know nothing about sparky things (blue is live, innit?). Draw your own conclusions.

Brown (L1), black (L2), grey (L3) and blue (N) are all live conductors. Live conductors include phase conductors and the neutral conductor.

There’s nothing unsafe about a Tesla charge point, it’s a simple dumb Chargepoint that is being compared to the darling of the charge point market, the Zappi 2 which is all bells and whistles.
Tesla charge points are very well priced for what they offer which is load balancing if there is another Tesla charge point installed, 3 phase ready, tethered and ability to open a Tesla car flap to access the charge port, oh and the look incredibly cool.
Like any other dumb charge point they do not monitor the house load so if you have the likes of an electric shower you will need a priority switch, that is all you will need as all RCD protection etc per any other plug in your house.

No. I pointed out that the joke was wrong as blue actually is live, along with other colours. It's you who this has gone over the head of.

Blue is live now?
I thought it was neutral?

Up is down, black is white.............what a time to be alive .

Kids, electricity is dangerous. Don't mess with it unless you are a highly trained & qualified electrician.

Everyone knows brown is earth, like the colour of earth.
Live is the green and yellow one. Because orange stripes mean danger.
Blue is Neutral, because of it's calming effect.
Did I mention I'm also colourblind?

I'm fairly sure that excludes most RECI electricians from performing electrical works :P

Neutral IS A LIVE CONDUCTOR.

You are mixing up the terms phase conductor (or line conductor) and live conductor. They are not the same thing. You need to look up the definitions.

"Live conductor:

"Conductor or conductive part intended to be energised in normal use, including a neutral conductor, but by convention not a PEN conductor or PEM conductor or PEL conductor."

Source: I.S. 10101:2020

I did warn you not to get involved in a debate which you cannot win. I have qualifications in the Design of electrical installations. I know the ETCI/NSAI Rules (and IET Regulations) like the back of my hand.

And again, common sense and sarcasm are lost on you.
If you can’t see the joke and the trolling of your posts in the above posts then best to get your head out of the books and have a read of reality and when you know them like the back of your hand then come back for a bit of banter.

Anyway, I’m off to swap out my third EV charger now. Same as an outdoor socket. Simple.

Won’t be there long. I’ll have it swapped out in 20 mins.
Have to get back home before inter county travel is banned again.

Some bright spark decided a new wave of lock down is required.

No good Electrician will discount you for running a cable (which you shouldn't have run). These are Restricted Electrical Works.

To further expand on this, electricians will need to get used to the cable run being in place. The new Part L Building Regulations will require the provisions to be put in for future EV charging and to enable the fitting of a EC charge point.

This to me means builders will be allowing space on the consumer unit and running the cable for future connection.

Want to help me attach some solar panels to my roof and wire them to an inverter and a diy lithium battery while you're at it

I have some spare coax I found lying around if you want to help you wire it up.

Thanks. I've spare external extension cord i bought in Woodies for the Xmas lights that should o the trick. Its IP rated.

Cool, I was going to wire the output of the inverter to a socket, that should work right?

Also, the green and yellow wire is optional right, I don't need to connect it to anything, do I? :P

Sure that'll do to wire your EV charger onto, what could go wrong?
