 Bigger Bigger  Smaller Smaller  Reset Reset

so i am working on a project that will require 15 relays to switch on and off 40w bulbs.  Not looking to use 15 plugs for all of them so I am looking for a god way to keep the wiring to a minimal.  I thought about using something to distribute the hot side between all of them and then plug in the wires to that.  Anyone have any recommendations on how to accomplish this or what I should use?  I was thinking a busbar or distribution block for the hot side at least.

Hi, if you use relay boards that have built-in terminal strips, it could be done pretty neatly. Something like these:



Specs and schematics on pages you can see here: http://goo.gl/8ZEQ8   These come on boards with 1,2,4 or 8 relays.

those are what I have but I still have to distribute power between all of them neatly and with just one hot and one neutral for all of them then connect the light to each hot and neutral for quick maintenance and if i need to change things

On connections like this I have made short continuous bare wire jumpers from COM to COM across a relay board, using heat shrink tubing as insulation between. Then another terminal block for all the neutrals. 

What country are you in?. The small terminal blocks used in Euro countries are very handy...

I'm in the US, and that it what I figured on doing just wanted to make sure that I was on the right path, just with all the relays and wires I wanted to be as organized as possible to avoid cross wiring or shorts.  I appreciate it a lot
