So I need to create a rig of 150'ish incandescent bulbs (15w) in 6 sets (25 bulbs a set) which can be manipulated via DMX on different channels.

 

I am not an electrician and all my work will be checked by one but my tutor said it would be something good to build and go an research on my own.

 

So I have 25 x 15w cables (1.5mm) in 2 meter lengths that need to go into some type of terminal block of some sort and come out as one cable that can be powered off of a UK 13A regular socket. 

 

At 15W x 25 that works out as 375watts per block. But in case I can't source 15W bulbs I will go with 25W which is 625watts at 2.717 amps.

 

My question is how do I go from 25 cables into one?

Something similar but with a lot more lights.

 

The wires into some type of screw terminal and then out to mains? With all proper neutral and earth in place. How would I got about this?

 

Thanks :)

Don't know how big they go but you can gang them together to get your 25 then fasten them to a board or whatever.

Yes those look exactly like something I need. Time saving and cheapish too! Thanks.

 

 

 

So just rig these thing in a radial circuit like a regular house hold? I'm assuming that should work?

 

Any electricians here? lol

Here i am,

i've done a thousand of this blocks of bulbs, it's very boring but easy. you have phase cable and neutral one, don't mess with colors because goes boooom! :D
you want the cable of every bulb to the main connector? if you use a dimmer channel for every block you can connect several bulb on a single cable (in-out) so you will have only 2 cables for block (12)
then go to a shop and buy a thing i really don't know how is called in english because i'm italian, it's a screw multi connector of different size. you put all the 6 same color phase wire in one and the neutral one in the other with another wire with the main plug or put 6 plugs one for every block in different dimmer channel.....

seem hard but i'ts very simple let me understand more: 6 blocks all to the same plug only one channel or separate?

I'd probably just do it with screw terminal blocks; you can make commoning bars for them reasonably easily with short offcuts of cable. Or you can probably find a commercial solution. The circuit itself isn't complicated.
