Has anybody used these matt-e products for EV charging points?

Former Community Member over 3 years ago

Is this brand any good ?

The supply source is a three phase T-N-C-S system. The load on the three phase distribution board is never going to be fully balanced so the options are to either to install earthing rods (electrode) or use one of these devices to avoid hammering rods to be compliant.

Just wondered if anyone had any experience with the brand.

Any other ideas also welcomed.

…the loads are only sufficiently balanced when charging.
It is common however to connect a car which only supports single-phase charging to a 3-phase charger, or occasionally a car which does support 3-phase charging via a single-phase cable. Clearly any design that assumes the car will draw a balanced current is flawed, so the balanced loads option is presumably only useful when the rest of the installation is both balanced, and hugely greater in load than the car. i.e. pretty much never.
