Rolec EV Charger from UK

    The Rolec has started to trip again. It tripped twice last week and when charging the car this morning, it tripped three times. RCBO is replaced, so wondering what should be replaced next (maybe the entire unit!!!). I'm not sure how much longer a type 1 charger will be needed, so if I can keep the Rolec going for the time being, that would be best. Anyone have a link to replacement parts?

    Did you replace the RCBO with a Rolec one?

    Even the green replacement ones aren’t very reliable. A good quality Hager or Garo one would be recommended.

    Which switch is tripping? The internal Rolec one or the CU?


    Regardless, first step is to open it up and check if the wires have got loose or if there are any scorch marks. Then decide next steps from there.

    RCBO replaced with the green Rolec one, as I had seen on SpeakEV that there were no reports of them being problematic...certainly not after a few weeks.

    The mini CU which gives priority to the shower is the one that trips the majority of the time. Very rarely would the charger end trip. I'll open it up later if I get a chance and check for damage and loose wires.

    I won't go through the trouble of replacing the unit. I have a 3 pin external socket I can use if need be. I'll be getting a Type 2 charger soon enough for Leaf40, so I may just replace the Rolec unit completely and perhaps I can can a Type 2 to Type 1 adapter to use it on the Leaf24. If I can cheaply fix the Rolec unit, I'll install a separate charger. A few options to consider.

    The green ones give trouble too but you are right, it shouldnt happen so quickly. Here are two examples.


    Let us know what the root cause is.

    The CP tripped several times since my last post and today I got some time to inspect it. The RCBO is is visually undamaged, as too were the wires. However, the neutral could be pulled out by hand, so I have made sure everything was tight this time. Fingers crossed that's the problem fixed. I have one of the cars plugged in now. If it doesn't trip, then it looks good, because it was tripping several times per charge.

    that would do it alright.

    No tripping since I tightened her up. That's a relief!

    Kcross is on the money there with the fault finding process, that loose neutral could easily do it- go through every cable in it, even the small control wires and give them a gentle tug- I do my ones here once or twice a year given the use they get.

    I have a back up unit here for parts, if your stuck let me know and I can lend you a contactor or power controller to help with fault finding. But 7kw’s coming back through a loose neutral is definitely going to cause you heartache.

    I had more drama on the CP issue yesterday. The mini CU which gives priority to the electric shower started tripping and wouldn't reset. I checked the Rolec and the wires were tight and no sign of damage. My intuition was that the constant tripping had caused a fault on the mini CU but I had an electrician take a look and he concurred that the RCBO in the mini CU likely failed from the number of times it had been caused to trip. New GARO RCBO was put in and we are back up and running. Can't wait to change out the Rolec now.

    I see Rolec have a new CP released. I will steer very clear of it.
