Just been to look at a new building for my company and noticed that the main 3 phase DB is located under a sink... Should I be worried? does it need moving?

Calm down :) will do when I have a min

I cant get a pic at the moment but its a CED Axiom consumer unit with 100a isolator and 10x RCBOs. The earth bar is sat on a fold of metal welded on the unit its self.

should I connect it to the earth bar then? what size? 4mm, 6mm?

I have a metal clad consumer unit and I have just replaced a breaker and noticed there is a brass bolt going through the side of the unit and its not connected to anything... what are these there for?

Hi, Two questions really if anyone can help... 1. I have a security light outside fed from the lighting circuit in the loft and was wanting to know if it would be safe to install a isolator for it in the loft so I can turn it off to change the bulb etc? if so does it need to be a 3 amp...

I dont unerstand... ALL control panel transformers I can find now are 55-0-55v

Hi, I cam across some Gewiss 24v sockets and plugs and also a transfomer from screwfix with both 110v and 24v plugs on it.... What are 24v sockets and plugs used for? there are not power tools for them. Thanks

The control voltage is 110v (the transformer is 55v-0v-55v) and the reason its so big is because it was the only one I had left without having to buy another one.

The transformer will provide a control circuit in a control panel (contactors, relays, lamps etc) the primary side will be protected by a MCB and the secondary either single pole MCB, double pole MCB or quick blow fuses Not yet sure on the correct protection for the secondary side.

I was going by what Jackrae wrote: "The concept of 55-0-55 is for the 0 point to be grounded (earthed) such that neither output terminal of the 110 volt secondary exceeds 55 volts with respect to earth. All UK 110 volt utility tool transformers (the yellow ones) are wired like this (or at least...

Thanks for your reply. So when wiring it all up I should connect the 2x 55v terminals to my equipment (to produce 110v) and the 0v terminal to earth?

Thanks for all your replies. There are terminals for 55v 0v 55v

Hi, I have a 500VA control panel transformer (55-0-55) that I want to use in a project, what is the max rated current of a 500VA transformer? I tried to calculate it and got about 4 amps?? Also on the primary side it has terminals for: 10v-0v-220v-240v what is the 10v for? Thanks

Even for 12v DC fed from a transformer?

Hi, I know that mains cables have to be within safe zones etc but is there any requirements for 12 / 24v cables? I need to get a cable to power a 12 or 24v light and there is no ideal cable route. Thanks

Hi, I have a room in my cellar kitchen that was used when the house was built in the 1800's for storing food etc. Its not my store room :) The room is below ground so naturally its not 100% dry but not that wet either. The walls are damp to the touch but not so much for me to start paying...

Hi, I need some LED GU10 bulbs to replace 10 50w ones. I have found that they are rather expensive! I have found these on Gumtree and just wanted to know if they would fit standard fittings before I try and buy them. I dont need them all but they may be of use for spares...

Hi, When installing a house alarm is it a MUST to have it on a fused spur? Can you not just install a 6A MCB to feed it direct and do away with the fused spur? Thanks

Hi, I am looking for some sort of temperature controller with ONE remote probe that will activate a relay when over the set temp and activate another relay when under the set temp.... Any ideas? Thanks!
