Hi, This may be off base for this list, but I'm going to give it a go. I'm setting up a 28 workstation computer lab at my school in a classroom that has two 20 amp circuits. The computers will be 200w P166's, and the lab will also house a PII server, HP 4000 printer, HP 870 printer, LCD projector and a good floor fan (the room has a southern exposure and heats up rather nicely). The head of our district maintenance dept called me tonight with concerns that two 20 amp circuits might be insufficient for what we're trying to do. The building was completely rebuilt in 1992 so that the wiring meets all current standards. Are we going to be in trouble if we don't increase the circuits and wiring to that room? I tend to think not as computers are not that power hungry during usage. It's the initial powering up that exerts a load. Any thoughts on the matter would be much appreciated. chuck finnigan [log in to unmask]
