Extension cords

Post by amcgowan »

I have an EVolution portable 10amp charger, which I usually plug directly into a household 10amp socket to charge my Nissan Leaf. Occasionally, when at a friends for example, I might need an extension cord. The EVolution charger instructions say not to use an extension cord, but if there is no other option that it must be of high quality, i.e. at least 2mm cores. Does anyone know if there is a manufacturer or supplier of 2mm-core extension cords with a 10-amp plug, as I would like to get one to keep in the boot of my car in case of the need of emergency charging. The nearest I can find to this at local hardware/builders supply stores is a 10 metre 10-amp 3x1.5mm core heavy duty outdoor extension cord. If i can't find a 2mm core 10-amp extension cord anywhere in Australia, I'm wondering whether this would be OK. Any product information would be welcome. Thanks.

Hi there-you might find it hard to get 2mm² as 2mm² is not a std size. 1.0 , 1.5 and 2.5 are though. A bit of history: 2.5 used to be the std for 15A cables, but about 8yrs ago some Chinese manufacturer decided you could do 1.5 if the cable was exposed to cool in the air. The rest is history... ☺
Your best option for EV spec extension leads now is to make your own. (I have a 100m roll of 2.5 heavy duty orange cable and fit industrial spec ends for all my EV leads. BTW: The industrial spec ends use screw connections to make firm connections. Much better!). PM me with your email address and I can send you an extended article from Renew on all this.
Cheers

For occasional use, like at friends' places, 1.5 mm² heavy duty would be fine. [ Edit: for 10 A EVSEs. ]

Maybe you could buy a 15 amp lead and replace BOTH ends with 10 amp fittings.

Hi all - re use of extension cords and power points, I did an extensive write-up about the issue at TheDriven. See:

Do you think this would do the trick for a granny charger?

Yep, that'd do it - assuming the charger is a 16A unit

2.5 mm² is possibly a little overkill. [ Edit: assuming a 10 A max EVSE. For a 15 or 16 A EVSE, it's a good idea. ]

Whether it is safe or not, depends on what you plug it into. The latest regulations require a separate circuit just for the EVSE outlet, and it needs 20 A wiring to the outlet (that part will be 2.5 mm²), as per Bryce's article linked above. It's unlikely that you have one of these available anyway. You will also need to address where the plug from the EVSE plugs into the extension cord socket; it may need an "egg" to keep out the rain. You should inspect the plugs and sockets regularly to see whether they are standing up to the daily high current use.

It really is better to get a socket for the exclusive use of the EVSE wired in, and make it one that takes the screw-on clear shroud (your EVSE plug should have a mating plug of course).

Edit 2: Of course, if this is for emergency charging, that's fine, though possibly a little overkill. That 2.5 mm² cord will be quite heavy.

I was just looking at an extension cord for occasional use. For example if I was at a caravan park (in a cabin) or at a friend's place.
On the subject of caravan parks, is it OK to plug a 10a EVSE into a 15a caravan plug?

Yes perfectly fine...
