Maybe take a look at this.....
Hi
@jamesie .
I have seen this video from Jordan, it is typical of what other owners have witnessed on there Rolec units.
The quality of the Rolec RCBO’s fitted to these units are of poor quality and are a diffident weak point.
The newer Rolec branded breakers with the green breaker switch, was an attempt to rectify the issue they had on the older blue switch coloured breakers that failed early.
Although the newer units are better, they still fail ( depending on use ) after around the 12 to 18 month mark.
Ask me how I know
.
I currently have a Garo branded RCBO installed in my unit and I am conducting checks on its condition every couple of months.
In fact, I intend to carry out a check today.
I think it largely depends on the usage you give your wall box, to how long the Rolec breakers are likely to last.
My previous car was a VW Golf GTE PHEV.
The battery pack was only small and the car would only pull at about 3.5 kw’s.
Therefore the load / time spent on the unit was only less than three hours Max.
When moving to the ZS EV - 99.9% of our charging requirements are done from home on a cheaper over night rate.
The car is about 15 months old and we have covered 12,000 miles in this time.
As you can judge from this usage pattern, our wall box is used on a very regular basis.
The unit can be pulling a load for up to 4 to 5 hours sometimes.
When the unit has been on for this length of time, if you place your hand on the top of the outer cover, you can feel the heat that is being generated over that long charging period.
This must have a long term affect on the life of any of the components inside of the unit.
This high load, delivered over a long period of time, is truly going to test the quality of the contacts inside of any RCBO.
This is what sorts out the men from the boys alright !.
The Garo branded RCBO comes highly recommended by other owners and EV installers alike.
This is why I have opted for going for one of these breakers.
Time will tell I guess !.
The unreliability of the Rolec branded breakers, has made me.completely paranoid now.
That is why I continue to keep up my periodical checks.
My wall box is installed on the internal wall of my integral garage, so in that respect it has had a pampered life.
Another reason why I check on its condition on a fairly regular basis.
I can out a FULL safe isolation process before entering the wall box of course !.
Jordan has natural stopped installing Rolec units anymore because his company and work load has increased massively over the last 12 months.
He can not spare the time to keep revisiting Rolec box’s that he installed to carry out warranty work due to early failures of the breakers.
Better to install a reliable unit in the first place.
