3 phase tennants meter

[thekingiam]

been asked to quote for a local car was firm who wants there own meter to check how much electricity they are using.
landlord has his own set up and they want to check they are not being ripped off.
have been told its 3 phase which i can't see a problem with, but was thinking of how some buissinesses tarifs are calculated a meter i put in would only show kwh used.
any other advise always welcome.

Are they being charged on an MD tariff? Would seem unlikely for a landlord's sub meter. Most modern electronic DB metering solutions can give MD and PF readings anyway.

havent seen customer yet so was looking into what i can ask them.as far as i can see its a lorry park with the car wash unit being the custommer. anyone recomend a 3 phase meter? my local wilts a bit vague in catalogue.

I reckon they will just be getting charged by the unit. Would be worth finding out though and then deciding whether el-cheapo refurb dial meter or a decent smartmeter is the order of the day

If they are being charged extra per unit it is worth noting that there is a maximum resale price set by law,to prevent unscrupulous people making a fortune.

just looked phill it says doesn't apply to buissiness premises?

Just buy a three phase meter or a CT meter install it after the landlords meter and compare the two values.
Use the cost of electricity and the standing charge applicable for that supply and supplier and see how much it should cost. Compare with bill from landlord.

just had a look wants a three phase meter to connect to a small water pump and also a single phase supply for outside lights etc. meter to be installed next to original supply, they have a three phase board supplying the internal workshop and i was wondering if i could connect the meter to this then from meter to a socket for outside water pump and also to a single phase supply.
socket is going to be next to meter.

 

[Richard Burns]

You have lost me there, why are you wanting to connect sockets to a meter?

The Owl energy monitors have the ability to have tariff structures programmed into them. They're available in 3-phase and they're easy for the customer to use. The OWL | Wireless Electricity Monitor Designed To Save You Money and The Environment

lol sorry, want to go from meter to a small three phase cu then from that cu to a three phase socket feeding water pump.also from that cu maybe to a single phase cu

 

[thekingiam]

thanks marvo but original landlords meter is old analogue so will put same cheap crap in for tennant.

Sudden realisation dawns I think,:confused5:

The tenants only want to monitor the usage for the three phase pump and the outside lights?

Therefore as you say get a 3 phase supply from the main board, connect that to a new 3 phase meter, then from out of the meter go to a new (small) 3 phase board, running the pump and the outside lights.
