FWL I agree with kendor that a double socket counts as 2. Please advise on where in the regs/OSG you are getting this info.

One spot light will make your kitchen look like a shower cubicle. Your electrician is giving you plenty of light in your kitchen. At 3M long I'd say 3 50W spots is enough (or 2 with your accent light fittings). I'd use the 240V type of spots rather than the 12V type as there's less to go...

The control box, sounder and each pir will have a tamper switch. I'd try shorting out each tamper switch individually at the control box for a test period.

To get as much life out of the battery as possible you should let the batteries run until discharged before returning the phone to the charger. Constantly charging the battery (before discharge) weakens the chemicals inside and therefore reduces the life.

Make sure the RCD is a 30mA (not 100mA)

Multi Why don't you add another consumer unit thus eleviating your dangerous actions of doubling final circuits. (16A for your lighting circuit and 40A for your socket circuit will not afford correct protection in both cases)

The switch on the front of an MCB is called the 'dolly' and although it stays up the inner workings of the MCB protection can remain protecting the circuit. Fire Alarm dollys are locked in the ON position by means of a dolly lock but the circuit is still protected. It sounds like the dolly is...

Dallas It didnt take you long to get into the swing of this forum.

Davey There is a 'Safe Isolation Procedure' for domestic isolations

Legrand is the Rover 45, Hager is the Lada, MEM and MK are the Rolls Royces.

Davey, Wiring lighting circuits in a radial circuit is the way its normally done and during fault finding or maintenance the electrician may think the supply to the lighting circuit is dead but it is actually back-fed through the ring. Its the same situation with socket ring mains but at least...

Do you see them blow or did they fail to illuminate when you swith the power on? Over heating can make them blow, but vibration (from someone walking on the above floor) or the lamps cooling down too quickly can also be a cause. If the lamps are recessed in the ceiling then you should...

Electricians who have served their time etc are as accountable for their actions as those who have no formal training. Anyone can be an 'electrician', so lets not blow the trade out of proportion. Domestic wiring is easy, but we like the idea of DIYers thinking its complicated. I'm just...

:mrgreen: I think we need to help those who think electrical installation is complex, not critique "expert" opinion. If we (as "experts") backed each others comments by added to them, then the forum could have some credibility. Lets face it domestic installation is no more complicated than...

There are standards for clipping flex which should be kept to. Thanks for the expected encouragement. :roll:

Putting trunking up may make your conservatory a bit of a dogs dinner. You could consider clipping cable directly to the surface and clipping it - 1. Unsheathed pyro has a copper finish but you'll need a good spark to do that 2. FP200 cable looks like flex but its more rigid 3. If your...

I'm looking for a decent CD Rom, DVD or modern video tape which covers basic domestic wiring diagrams, calculating current carrying capacity, etc ... for a class of mature students I teach domestic wiring to (so, something that's not so much about the IEE regs but about the practical side -...
