Strange UMC behaviour (NON TESLA RELATED)

[Tevvy]

Hi all, slightly off topic with Tesla but here goes.

My wife has bought a brand new Renault Zoe, and it doesn't come with a charger, so she's been charging it from the 3 pin plug on my Gen 1 UMC without issue for weeks.

Given how slow it is, I thought I'd try with my blue 32a commando attachment (this is what I use for my Model S, and get a solid 7.4kW). However, it instantly trips the consumer unit breaker (which is 40a).

Given her car has a 22kW onboard charger, there's no reason this shouldn't work is there? There are no settings on the Zoe to change anything like draw or amps etc.

Where should I start? Is it never going to work, or would you think something is wrong? Where do I start to diagnose?

Thanks all for any help.

This is a strange one for me. I use the same for my X. The connector you use regulates the max amps off the UMC so it should not go over the 32Amps.

Can you reduce the Amps in the Zoe to see if a lower setting works as it works with your other plug.
