Flood lights

[Ashley Williams]

Hi guys

Im new here im currently in my first year on elec installation at college yale in wrexham to be precise.

Im wanting to wire 2 500watt floodlights but they need to be portable so i want them on a normal 13amp plug top. So I will obviously need to use flex so am i right in thinking that i need 1.5mm2 flex?? also what size fuse will i need to install in the plug top. Asuming it is ok to wire 2 500 watt lights like this i cant see why but im no expert.

Thanks Ashley still learning.

Are talking two seperately wired portable lights on plugtops?

Wired on the same circuit. Both off one plug top

2 x 500watts = 1000 watts / 230V = 4.34A 5A fuse will do.

Flexible 1.5mm cable rated at 16amps.

Where are they to be used?

These lights can get very hot and heat resistance cable maybe more suitable?

Basically i race radio control cars so everyweek we rent a hall. But last week the hall was rewired with new lights but the new lights are in diffrent possitions to the old ones. So they dont light up our pitting area as well, so we asked if we could wire in a couple of flood lights they said no. So we asked them if we could put the lights up but not be hard wired in, just have them on a socket and then take them down each week they said yes aslong as it is safe and done properly.

Each with a seperate plug or you connecting both of them to the one?

They will each require a seperate plug top.

I would like them on one plug top but if that just isnt possible then it might have to be two. I asume it would be ok to wire 2x 250 off one plug top?

Never good practise to wire more than one appliance off of one plug top.

Use your P=VI equation to work out your current drawn, it will be good practise for college.

I got the idea from a portable teloscopic flood light we have sort of thign you might have on a site that has 2 on one socket is there any sort of junction box i can use to connect two units to one socket. I just dont want to use to many sockets up in the hall.

By the time you've bought the lights cable etc and made them up it probably cheaper to buy one of those tripod types your talking about of the shelf.

 

[Ashley Williams]

But that wouldnt be tall enough unfortuantly.

Why not use something like this and use an extension lead?

Stand & Tri-Pod Halogen Floodlights

 

[Ashley Williams]

It will be about 15 foot in the air so yea i could use something like that and maybe put a extenstion lead in the roof.

if u do opt for making your own as long as u wire them in series you will be fine as people have said a 5 amp fuse in your plug top should be ample current but you will need heat resistance cable which isnt cheap so if the tripod works out cheaper then probs best option if suitable for your needs.........

 

[Ashley Williams]

Just for my own knowledge why would i need heat resistant cable?
