Hi Jimmer
You have no doubt sourced something by now.I have come accross plastic back boxes,but only on rewires,stripping old stuff out,so I can only assume they have been discontinued perhaps due to the scarcity of lime plastering these days.Perhap national trust could help...
I have to agree with other posters,and just make it TT. Its not such a big issue these days anyway as
nearly everything is on an rcd anyway now.Just means you should leave out the link to the sheath and install your earth spike. You are relying on your rcd for your disconnection times to be...
Perhaps it already was TT,hence the reason that the 16mm link was left out and the reading at the socket was 2.03ohms....Perhaps there was an earth connection to your earth spike from your existing consumer unit..This could have been in the form of an old green cable as small as 6mm which I...
agree.!!!
Normally on a tn-cs the neutral is earthed at numerous points on the way back to the supply transformer......(pme-protective multiple earthing) whereas on a tns system this is often not the case.
Also I'm not quite sure where you have performed this tn-csing as usually this would...
Hi Lawrence,
The thinking behind this requirement is that if you were to wire your lighting sockets into the lighting circuit,ie switched from normal light switch,using standard 13amp sockets, someone could come along and plug in a heater,kettle or other high current using...
Hi,I can't think why you would have to "double the wattage" but I recon I'd go for a standard 600watt
dimmer switch....and by the way the buzzing tends to occur when they are turned down to the minimum,this can vary with make you choose.
If you are working, your boss will probably be able to get them for you a bit cheaper at the wholesaler he uses,as he will be getting discount on his account,and probably will be able to claim the vat back too.They probably won't have all in stock but can order in for you.
I would like to help you but don't really understand what you need this information for..What country are you located in? The information that you requested will not be the same every time,it will depend on where you are,the transformer type,supply system grounding etc. The installation is...
Hi,
I've got a wee job to do in an office in town for which the landlord is requesting a nic cert.
The office in question is currently (power) supplied via a 6mm(45amp fuse at origin).It feeds a 4way rewireable fuseboard supplying 4 radials.My job is to relocate some sockets and install...
LOL>>
(I think however I would have used split concentric cable,as its got full sized 16mm earth and I think it would probably not need 30ma protection)You don't mention if the origional installation is TT orTNcs
Yes pehaps,if he were to use a 3 position H.O.A.(hand-off-auto)But it doesn't look like thats what we have here.If the time clock is dodgy and not switching off ,I'm assuming that it's being switched off by the manual switch on the timeclock itself..as w ell as the plateswitch.
Iceman...
400volt lights? is that a missprint? You should be able to temporarily alter the time off to a time when you are there to see if they do indeed go off or not....But I would recon that if I'd paid for it I'd expect it to work.Also I'm not sure why you would need to have it controlled by the...
I've answered this before SEVERAL TIMES just try googling SHOWER PRIORITY SWITCH. They are not cheap.It is also possible to make up one yourself. But I would think you would be better fitting a shower pump and then all you would need at each shower point is your mixer valve.Of course you also...
Hi BS
I always where possible use 10mm split concentric cable for showers,far easier to work with AND is uv protected.You will probably need to source it from cable suppliers rather than your local wholesaler but there is very little cost difference and you dont have to buy it by the...
Hi,
There seems to be a little confusion over split phase and two phase.I will attempt to provide clarification.230/460volt would be split phase where the 460 volts are tapped off a supply transformer from a single phase sourse,ie the primary would be supplied at a higher line voltage(1 live...
