HELP! 2 way 2G dimmer with downlight!

[salmanhamid]

Hi All

Apologies if it is a basic question and has been discussed here before.

We are putting new spot lights in our bedroom and I am in the middle of buying all the stuff we need, we are putting 9 lights for the bedroom, GU10 240V with 50W lamps, outer 6 will work on 1 dimmer and inner 3 will work on one. My question is, is this dimmer suitable for what we are trying to do cause Im unable to find 2G 2W decorative dimmer in 400W all I can find is 250W one

And we certainly cannot have dimmers on both ends, has to be switch on one and dimmers on other?

You have two controls to consider one governing 6x50W = 300W and one governing 3x50W=150. So 1x400W and 1x250W should do for the dimmers and then a 2g2w switch at the room entrance. The real question is which side of the bed do you place the dimmers

Just a little warning.

When GU10 bulbs blow it creates a small surge that sometimes takes out the MCB/RCD and can also blow the dimmer switch at the same time.

This happened to a 1000W dimmer at my sister's house earlier this year.

According to the instructions, posted on the pages, they're one way switches.

No you don't have to tell them exactly what you are having. Part P only applies to new circuits, alterations in kitchens or special location in domestic dwelling premises

That is absolutely not true.
Building Regulations Part P relates to electrical safety. ALL electrical work done in domestic premises must comply with Part P.

By law, SOME of this electrical work is notifiable to the local authority.

The list of what is and isn't notifiable is contained in the Part P document. Some downlight installations are notifiable in any room of a house.

Some downlight installations are notifiable in any room of a house.

Only ELV lighting that isn't CE marked and pre-assembled is notifiable as i said above (post #11). The OP is using 240V GU10 downlights.

What Dillb was saying is that this particular job is NOT notifiable as it doesn't include the provision of a new circuit, isn't a special installation and isn't in a special location.

ALL electrical work done in domestic premises must comply with Part P.

All electrical work done in domestic dwellings must comply with BS 7671:2008. Complying with Part P means notifying to LABC when required to.

look on tlc direct website, you can get Master and slave dimmers made by varilight in their IQ range
these also have a remote control option, also how about using LED's? bit pricier but you wont have to worry about the wattage, as you could use 9 or 11 watt lamps, just make sure you get compatible lamps and switches.

 

[telectrix]

i too would go with GU10 LEDs. ( 5watt 0r 7watt ) but make sure that they're dimmable and the dimmers are suitable for LEDs

 

[salmanhamid]

I don't mind LED but then I'll be back to square one to find compatible dimmers and bulbs in the finish I like

I don't want to be pedantic, as I am new around here, but I run across this confusion a lot.

You and dillb should read what the regulation says. In particular P1.
P1 says
"Reasonable provision shall be made in the design and installation of electrical installations in order to protect persons operating, maintaining or altering the installations from fire or injury."

The main method adopted by the industry to comply with P1 is to work to BS7671, this calls for the electrical work to be inspected, tested and the relevent certifion issued.
BS7671 is mentioned in the legislation as one way of complying with electrical safety.
If you don't work to BS7671 (or another recognised standard) you may find it difficult to prove compliance with P1.
P1 is a requirement for all electrical work in domestic dwellings in England/Wales whether it is notifiable or not.


Notifiction of certain electrical work is also a requirement of Building Regulations Part P. Part P is not just about notification.

As BS761 (along with other parts of the building regulations) is mentioned in nearly every paragraph of Part P, I say again. All electrical work in dwellings should comply with BS 7671:2008 and certain jobs should be notified to LABC under Part P.

Most of Part P is telling you that you must comply with other regulations. The only thing you must do with regards to Part P alone is notify relevant jobs to LABC IMO.

agreed^^^^^^. and certification is optional if the job is replacing an accessory without altering a circuit.
