Am I correct in thinking that would be the case in a typical residential context but where the meter is a HH meter then no switching (to a night rate circuit) is needed because the meter will record day and night rate consumption?

Couple more pics: 1. Supply meter location 2. Bank of sub-meters used to recharge weekly consumption to owners/occupiers. 3. Close-up of one sub-meter With regard to 2, I presume that the 'low' and 'normal' registers of the sub-meters are separately wired to the 'day' and 'night' circuits at...

This is the supply meter.

I am chairman of owners' committee for timeshare development of 11 apartments. All heating is electric night storage radiators and we are on a dual rate tariff. I've recently obtained half-hour meter reports from the electricity supplier and noticed a metering/billing anomaly. The night rate...

Sorry if I'm slow to catch on here. Is your suggestion that an electonically timed/controlled panel heater system that turns on/off according to temperature settings could be more economic than night storage heaters that (mostly) use night rate energy. Is this the type of heater you have in...

I'm chairman of the owners management committee. I own two weeks in July so not so much of an issue for me but £250 for one week!! The windows are all double glazed and relatively recent (<10 years) but there's a lot of them as it is a waterside location. Even the cheap rate electricity is...

I'm looking for some pointers on electric heating in an apartment block comprising 11 apartments constructed ~35 years ago. It is a 'shared ownership' development so has different occupants each week. Each apartment is two bedrooms (one en-suite) with living room/kitchen and a second bathroom...

Fair enough. But this is data for the transformer I've installed. 0V, 10V, 12V,16V Output Voltage (NEST / RING Doorbell Compatible) Bell transformer is for use in consumer units with an operating voltage up to 250V 50Hz. and has a power capacity of 8VA. It complies to the following standards...

Hmm. I see the argument but the installation manual is quite clear that existing transformer can be used if 16-24V. The video is not recording continuously, only when activated by motion detector or bell push.

I am planning to replace existing plain vanilla doorbell with a wired video doorbell. I want to retain the existing chime, which requires 8-16V AC supply. The video doorbell requires 16-24V and 10VA. Existing doorbell setup includes a Honeywell remote chime that specifies 8-12V supply. I...

Hi. I hope I can get some help with diagnosing a problem with my CH/DHW system. These are the facts. Boiler is a Potterton Suprima 80 (~ 20 years old but still in good condition) DHW is stored in Megaflo cylinder (unvented system) DHW is on a water circuit separate to two CH circuits serving...

Thanks Sunray and yes, I was thinking of a 2P RCD + 63A fuse. I haven't yet found a 2P 63A RCBO. Below is a wiring diagram of what I envisage based on the discussions so far. Couple of NBs: (1) The earth connection from the genny to MET will be via the 32A connecting lead so not permanent...

Is the purpose of that to mitigate against the lead being used in a setting where the N-E link isn't needed?

Yes, I corrected that. The fuse would be the OCD for the SWA. There is a breaker on board the genny that should protect the connection cable (it should trip if load exceeds the genny's capacity, which is 25A. I suggested the 2-pole RCD in place of the RCBO recommended by Simon and to be the...

Many thanks Simon and John. It seems to me I should only try to make 'this' genny safe to use. I am the only person who would be at all likely to operate the genny. If I sell the house, it may or may not include the generator. If not, I will place a suitable warning on the inlet/changover...
