In this can, I have terminated all of my contacts onto 66 blocks. I used 25 pair telco cables to run these over to my Elk can. All of the contacts that require power are connected to wiring blocks, which are connected to a power distribution unit. I had to be carefull not to exceed 250ma on each leg. Most of the motions and glass breaks were 20 or 25 ma, but the gas sensor was 83ma! Below that is the Aprilaire box, telephone distribution, and cable distribution.
