Off peak supply / 3 phase / commercial...

[sythai]

Evening All...

Just after a bit of assistance please, new one for me.

Had quick glance at 3 phase CU today, reference storage heater upgrade.

Unlike a domestic set up couldn't see a separate meter for off peak.

But what I did notice was a couple of little grey cables coming out the right hand side of the meter, and what looked like the same sort of cable going into A1 of the control circuit for the heaters ..? Will trace it all out properly when I get all the covers and trunking off.

Any thoughts please.

Cheers Sy

My guess is that the meter is a multi rate meter that also has a time clock facility built in and the two thinner wires are a switched feed that becomes live when the economy 7 kicks in.

Makes sense looking at the way they are identified. I can't see if they are T&E or single and just use the existing neutral already at the heater.
