Type 2 cable for Phase 2

[SiW80]

Will a 16amp 3 phase 11kW be suitable for charge at an old ChargeMaster wall box (at home) and out and about?

Cheers!

Yes but you will only get about 3kW as I believe the Phase 2 is single phase.
I wish they hadn't called it phase 2

Ok - should I have got a 32amp 1 phase 7.2kW cable?

If you've already got a 3 phase cable it will still work with a single phase supply.

Ian, Ian Ian, what are you saying! A 16 amp cable will have 2.5mm conductors, if that is put into a 32amp single phase which should have 6mm conductors one 2.5 wire will be pulling too much current for its capacity. It might get a tad warm! I,m assuming Siw80 has a single phase wallbox and not 3 phase.

Correct single phase but will need to check the breaker size

For the Phase 2 on 7.2 kw charger in the car , you,ll need 32amp breaker and and specific RCD with minimum 6mm cable throughout on a dedicated circuit. Optional use of surge protection and specific earthing is also recommended. A trusted electrician should be your first port of call. Good luck with it all.

You mean the cable won't tell the car that it's only rated for 16A? (Cables tend to have a resistor in them, the value of which provides info to the car's onboard charger).

I might have misread the question I thought it was about a Type 2 EV charging cable.

 

[Jomarkh]

The resistor in the type2 cable will tell the EVSE how much power to offer the car.

If I may quote Eric Cantona " When the seagulls .........." It seems the little fish has been thrown back in. It appears I did not consider the pp and cp connections and their actions on the OBC. Lets just call me an idiot and have done with it!

The charger was installed a couple of years ago for my old Zoe

Sorry, SiW80 I do not have any knowledge of the Zoe charger, or anything else it would appear. But whilst the relevant members are involved can I hijack your post with a slightly relevant query. I have a Morec granny charger with a type 2 plug, the cable is 2.5 mm 3 core with a 0.5 communication wire, all good. On the wall plug side it has the same cable going to the factory moulded 3 pin plug . Where does the 0.5 wire start and terminate on this side of the granny charger, thanks.

 

[siteguru]

It doesn't ... there are electronics in the "box" which does the communication with the car. The 3-pin side is simply for the electricity supply (and earth) so doesn't need that comms wire.

Thanks , thats what I assumed, but I,ve recently doubted my sanity! I imagine its quicker and easier for Morec to use the same cable each side of the granny but not use the 0.5 wire on the supply side, leaving it redundant. But with a factory sealed system you never know!

 

[siteguru]

If the cable does have the wire on the 3-pin plug side, then they'll simply not terminate it ... or maybe they'll tie it to the earth pin just so it's not floating.

What is the spec of the MG Type 2 cable? Single phase, 32amp, 7kW?

 

[siteguru]

Yes, as far as I know.

 

[SiW80]

Yes, as far as I know.
