    How many watts can a 300w rated Legrand dimmer really handle?

    I've got some Legrand dimmer modues, 7354-46. They are rated at 300w but with the setup that I have I'd really like to use one of them on a circuit with a load of 420w. I've read before that MK dimmers can handle 200% of their rated load. Anyone know how much these Legrand dimmers can handle...

    Ceiling is not 'fire rated' so do downlights need to be??

    Hi guys, I'm doing a load of EICRs for the firm I am working for. They look after lots of different properties and they are all due EICRs. Many are installs from 10-15 years ago and feature non fire rated downlights in flats with habitable space upstairs. The ceiling is single skin regular...

    Inspection question

    527.2.1. A flat with a multitude of downlights. I am not convinced that the G5.3 fittings are firerated and they are mounted through a double boarded ceiling which is a fire barrier (confirmed with the original architects). The fittings are made from a pressed metal which is very thin and...

    90C rated accessories

    I'm going to stick my neck out here and put myself up for ridicule. Given that SWA rated to 90C can only be run at said conductor temp IF the accessories its connected to are rated to that temp also. Are there any sockets etc (ideally metalclad) out there rated to that temperature? As I've had a...

    fire rated downlights

    I'm fitting a number of GU10 down lights and am having a problem with the earth conductor - these units have a cheap nasty terminal block with all three connectors presented - L/N down to the usual moulded GU10 plug, no worries there. The earth is riveted onto the side of the downlight itself...

    IP rated or not?

    Hi all, As an apprentice I know a small amount about IP ratings and would like advise on whether the bathroom light in my parents house is IP rated. My thoughts is that it does not look IP rated and I can't see an IP rating on the fitting. My parents seem to thing that it was an IP fitting...

    Calculating 3 phase current

    I understand that the formula to work out a 3 phase current is I= P/(1.732 * V * pf) I have a 3 PH+N water pump rated at 4kw, so I= 4000/ (1.732 x 400 x 0.8) I= 4000/554.24 I= 7.21 Amps per phase The problem I have is that the label on the pump control says that its rated current is...

    THIS is what happens when you exceed the rated wattage....

    Went to change a light fitting today for a couple who'd just moved in to their new house. The fitting was rated at 2 x 60w. The lamps actually in the fitting were 2 x 70w. I'm used to seeing ceiling-mounted fittings with a little heat damage, but this was scary. The timber it was mounted to...

    LED fire rated downlighters - 12v or 230v?

    I apologise if this is a stupid question! What are the benefits of using 12v LED fire rated downlighters, over 230v LED fire rated downlighters? I assumed that this is more cost effective using 12v as although they are more expensive they last longer and use less power, correct? Can anyone...

    Domestic CUs have built in wiring of 16mm2 but...

    ...what if you had a 100a cutout?! So for e.g your tails (consumer and dist.) are both 25mm2 and you have a cutout fuse that is 100a - technically the cutout fuse is the only thing protecting from itself to the bottom of your mcbs. Most consumer units have the "built in" cables that are 16mm2...
