SINGLE PHASE LOAD SHEDDING

John Peckham

I design LV electrical installations including large current hungry domestic installs. I am frequently having single phase supplies upgraded to 3 phase for these houses due to mutiple ovens in kitchens, ASHP, AC units, EV charging etc loads. If I cannot get an upgraded 3 phase supply I want to use load shedding so that the single phase supply capacity is not exceeded. I am looking for a simple 3 phases device with current coils on the supply that will disconect chosen loads. I do not want any fancy electronics or PLCs etc. Can anyone recommend any product on the UK market that will do this.


Thanks

JP

    Well, the EV Charge points in house with TNCS use a load monitoring device-  that I've forgotten the name of it right now - that certainly uses a mains tails amp monitoring sensor that cuts the EV charger off if the amperage exceeds a certain value, say 100 Amps and wont let it turn on again until the amperage gets to below say 60 amps. Something along those lines.

    One of those units would work for a single load for sure, even if its primary function is meant to be for diverted neutrals..........I'm sure the manufacturer does more options and can tweek the settings to suit.
