On looking at just what runs off what circuit in the machine room, we came to the conclusion that it is not surprising that breaker #11 has been popping occasionally. Neglecting the 220V circuits and the ones running outside the machine room, the list of which breaker powers what looks like this (they are all 15A breakers): no. location powers --- -------- ------ 1 under floor tty40, Sanders 3 under floor Camac crate, RJE 05 5 East wall Versatec, card reader 11 South wall E 44, 05#1, 05#2, floppies, magtape, Star Ring, misc. 13 South wall W 44 expander box 15 West wall #1 2 Gandalfs, 2 Bell modems 17 West wall #2 1 Gandalf, 3 fast modems, clock 19 West wall #3 console terminal 21 West wall #4 nothing Circuit #11 is very clearly overworked, and there is a general shortage of power on the South wall and a surplus on the West. Another item in the list of things we'd do differently if we were renovating all over again! More immediately, Monday backups will run extra-long so we can rearrange some of the power cables. Among other things, we intend to run a cable from #21's outlets (behind the tape cabinet!) to the cpu area.
