Outdoor lighting options
I want to put in lights in my garden but we don't have an external electrical socket. Wondering if it's acceptable to run outdoor lighting from an internal electricity source. What are the regulations for outdoor lighting?

Minimum requirements: 30mA RCD protected socket outlet, water-proof lights( IP56 ideal), if wired in flex this should be in the ground protected by damage, or clipped on the fence --- not on the grass... a nice summer job for a electrician :) Cristian

Approx price to fit a mains powered smoke alarm
Would like to know a guide price as to how much it would cost for an electrician to fit a smoke alarm in a domestic property.
Additional info:
The property is a two bedroom flat on one floor. The fuse board is located in the hall by the door. I would imagine the best place for the smoke alarm to be the hall (off the hall are two bedrooms, a bathroom, and a living room which leads onto the kitchen). I would prefer if all cables were hidden.- Yheathera 22nd Feb, 2011 Electrical

Fault Finding
Hello,
I now think I have a problem with electrical wiring in my flat.
I use electricity for water heating and for my panel heaters (radiators) … and for anything else , no gas.
Having just recently returned to my own flat after living away for work, I have realized that all 3 of my panel heaters (radiators) are no longer working.
I got the feeling that it is wiring issue or the manual timer (which is located in the store room and control all operating time for all 3 panel heaters) might be at fault. I have now turned the MCB switch for the panel heaters off.
The other day, the manual timer for my conventional boiler blow up when I turned the MCB switch for my water heaters from off to on. (See earlier job / questions posted)
Today, I turned on the corridor lighting and one of three lights went off!
I changed the bulb but it is still not working. I presume it must be another wiring fault.
Please could someone advice me on this matter?
If possible, please also advice me what I should expect to pay to get this looked into.
I was told such extensive job would be very costly.
Any further advice would be appreciated!
Regards,
Ray

Relocating Consumer Unit
I am planning on installing a Velux balcony system on to a flat roof area but my Electrical consumer unit & meter is in the way. Can this be moved to a new location by a suitably qualified electrician or do I have to contact EDF my regional supplier. If I have to use EDF any idea of the cost?

you need to call an expert to have a look at the actual position of the main cable. Nothing can be said from an email.... regards, Cristian

Downstairs lights keeping tripping out the fuse box
Woke up this morning to find the downstairs lights had tripped. Flicked them back via the fuse box and all was well for about 2 minutes until they tripped again. This went on for 4 to 5 resets before i thought i might be out of my depth. Its the whole down stairs affected, which is covered under the one switch on the fuse box. Not had a problem before. All of the lights do come one when the switch is reset, so there isnt a particular light that seems to be the problem.
Any thoughts?
Thanks for your time.Mark

Hello mark ,
Best thing is to get an electrician in. He needs to test the insulation of the cables, and the following can be found:
- a loose wire in a light / switch
- a insulation failure between the conductors.
Very rarely there is a faulty circuit breaker.Regards,
Cristian

Why have my halogen lights stopped working?
Yesterday i switched my bedroom lights on and it tripped the fusebox, i then reset the fuse and it did this again. Since then the lights have not worked. They are 2 separate halogen spotlights each with 3 bulbs. I have changed all bulbs and it still does not work. Any ideas?

There is a insulation failure due to wires being on top of the light fitting/s otherwise wou should find a loose wire in the light/switch.

1000 watt dimmer switch buzzing and over heating
I recently got my house re-wired and in the lounge I have two sets of low voltage (24v) spotlights. One circuit has 12 x 50 watt bulbs (600w) and the other circuit has 6 x 50 watt bulbs (300w).
I designed it this way on the back of buying a 2 gang 1000watt dimmer switch which states that each gang can take a minimum of 150 watt and a max of 1000 watt.
However when we did the big switch on both switches give off a very loud buzzing noise (too much to live with) and in fact the smaller load 300 watt switch gives off an even bigger buzz and after 10 mins the light starts to flicker and a burning smell comes from the switch.
I first thought it was a faulty switch and the supplier sent me a replacement free of charge - but when we switched it over it still has the exact same problem.
All the other circuits upstairs were wired the same way (transformers with each light) but with lower loads (up to 300w) and all work ok off standard dimmers - Can anyone explain? Do i just have a cheap 1000 watt dimmer as it was off ebay or is there a bigger under lying problem.
Problem is house is now all decorated nearly and not simple to run another cable
Any help will be VERY much appreciated

Make sure the transformers for the lights are dimmable, if that is okay, then buy a better dimmer. Would suggest crabtree, MK, or volex.

The neutral meter tail incoming to the consumer unit is made up of 10 x 1.5mm cables. Is this safe or should it be a single core insulated 25mm cable?
This is a new building.

Realisticly You can only have this for a very short term. It should be the same size as the live conductor.
The tails are starting from 16mm

Im having a new supply fitted the cable runs 360m and needs to be able to run 2 large mobile homes, garage,around 6/8 lamposts, electric gate.
They are giving me 10 KVA(100amps), I dont think this is enough and the electrical comapny has asked me to calculate it, what would be a sufficient amount to be able to run everything I require? EDF have told me they may have to change part of the cable from LV to HV

hello, 100A single phase supply is equivalent to 23kW or about 22KVA
the guy was saying that you need 80A for 9KW is wrong
the calculation is : (current 100A x voltage 230V) = wattage 23 000 W- Christian V Electrical LTD 16th Mar, 2012
