sangamo round pattern time swich connection to meter

doningtonphil

Hello. I need some advice and not a telling off.

our friend is an electrician. He has fitted a new consumer unit. As we have removed two night storage heaters we decided that those circuits could go onto the new board and become regular sockets.
That left the separate fuse box redundant. The wire from that fuse box went to the sangamo round pattern time switch so that the heaters operated off peak only. He assumed the time switch was for the sole purpose of the storage heaters so promptly disconnected the time switch from the dual rate meter. Needless to say the metef stopped switching to low rate overnight.

He has reconnected it today but the time switch has just activated but the meter has stayed at normal. It is obviously wired up wrong.

can anybody provide a wiring diagram or advice to resolve this?

Many thanks

Sounds like he is not an electrician more of a cowboy ensure he doesn't leave hay by it when he leaves

If you google “sangamo round pattern time switch” then click on the pdf for tlc-direct.co.uk or click link below shows you all you'll need not sure he'll understand it though

Thanks brightontraveller.

the wiring diagrams show live and neutrals coming in, presumably from the meter and then out to a load (which in our case is no longer there ). Does that mean there should only be 2 lives and 1 neutral between the meter and the time switch ?

If they don’t’ understand it with a wiring diagram I wouldn’t allow them to do any works at all? Reading your post it also appears they have been playing around with electricity suppliers meter these are sealed “disconnected the time switch from the dual rate meter” that’s a big no no which points towards them being totally clueless so wouldn’t like to advise you as they don’t understand the basics you can say put live here neutral here etc or as wiring diagram states “On all 4 pin models (excluding Model Q563),Where separate supplies are not available for the motor and switch circuit, fit a link between terminals 1 and 3” I’m not even sure what there trying to do timers are there allow power at certain times cheap rate etc is set by the meter and your supplier ? It would be dangerous to to tell you anything as god knows what they’ve connected and where before it?

thanks brighton


i know what you are saying. my reply to your previous post was just a case of me trying to understand how something works rather than them struggling to understand what is in the link

from what I can see, the wiring diagrams in the link provided earlier are all assuming the time switch is being used to control an external load - which ours was as it was controlling the storage heaters. Our electrician assumed that as he was taking that circuit away that he no longer needed the timeswitch and disconnected it from the meter.


He didn't realise the timeswitch was actually telling the meter when to switch from normal to low for economy seven for all of the circuits inluding the main board (rather than just the storage heater circuits).


All I am wondering is if there is a wiring diagram for just the timeswitch controlling the dual-rate meter.

Just call out your Electricity Board, admit what happened, say sorry, and ask if they can help. Don't fiddle any further.

Unfortunately it could also be seen as attempting to manipulate the electricity rate peak low etc:eek: Maybe friend family neighbour etc have the same set up removing the storage heaters and fuse board aside if cables were to be put a back they same as they removed then it will work apart from all the seals being broken?

Thanks Brighton, that's a good idea.

Also, i take it i might contact scottish power as the meter 'owner' rather than EDF who we pay the bills to.

Thinking about it, or neighbour a few doors down is an area manager for scottish power. Maybe i should confess to him and see if he can help.

Hello


An update.


I contacted Scottish gas and confessed all. They sent out an engineer. However he said he couldn't fix the existing installation because there was a cable missing going into the consumer unit. I said the same number of cables go between the metre and main consumer unit as there has always been (2, a live and neutral).


He was adamant that there would be two lives, one for electricity to flow along during normal rate and the other to flow along at low rate. Is that right? Surely the electricity always flows along the same path. The only thing that changes is which set of numbers on the metre are affected by the electricity flowing through the metre rather than being diverted along a different cable.


The long and the short is that he said he had to take the existing dual rate metre and timeswitch off and put a new single rate meter on and it is impossible for me to have economy 7. Is that right?
