Long extension lead for ev granny charger

[Livingthedream]

The test button flips the RCBO off so I’m guessing all seems well, I’ll order the cable and bits tomorrow

Thanks for all your support

I occasionally use a similar setup to charge my van... it works fine, but I'd keep an eye on things the first few times to make sure there are no bad connections that cause things to get too hot.

Theoretically... you should be using 13A sockets that are "EV" rated as these are designed to be used for a high load for long periods of time.

Some (maybe all ??) "Granny Cables" have in-built temperature sensors in the 13A plug tops that will trip out if getting too warm... but your extension cable will introduce new connections points that won't be temperature monitored.

Do I need to check the plugs and sockets or do I need to check the consumer unit for heat as well?

The CU should be fine if properly installed.

Just check the 13A plugs are not overheating. New sockets of decent quality out to be OK, but any loose-fitting plugs or tarnished connections can cause problems on sustained high loads.

Important to fully unwind the cable from the reel, or it will heat up, melt and catch fire.

The cable will only have around 1 meter play so it won’t be coiled up, it all sounds scary when you think about it.

hopefully it will only be a matter of weeks and then it will just be an expensive extension lead that probably won’t get used.
