Domestic 415V 3-phase supply. ABB Meter and Horstmann timeswitch

240/415 V; 100 A supply from a large townhouse in central London.

The building is heated primarily by night-storage heaters, hence the reason for providing a 70 kW supply.

Meter is an ABB E 43B3B-RH
Timeswitch is a Horstmann V Mk7

Note that a separate contactor is needed to switch the heaters as the time-switch is single phase and would not accept the load of the heaters.

Individual phases from the unswitched (main) supply go to individual 240 V distribution panels on each floor of the house (not shown).

Awesome video. Nice meter and time clock set up.

Thanks for showing and the detailed explanation of all equipment involved

Very Nice!! I wish that my GEC 3ph, dual tariff meter was direct-wired, I may have been able to use it then! :-)

The thing is though, my one needs CTs to work correctly. OK, so that does mean that it'll be able to take a bigger load than this one, which I suppose, in the right setting, is a bonus.

ALSO! Nice to see a Horstmann Vmk 7SRS in service there! YAY! I own a few of those, as you probably know by my vids.

Nice upload, I do like those MEM 'exel' isolators. Drool......
