One thing that has never been my forty is electricity. I'm trying to find out what's the best way to see if my office will safely handle everything I want to plug in without overloading it and setting it a-blaze. My office/layout room has 5 AC outlets and is on a 15amp circuit in the breaker box. I have two computers, 3 LCD monitors, scanner w/psu, DSL model, wireless router, printer, and ceiling fan typically running 24/7 already in the office already. How would I go about calculating what the office is capable of safely running without overloading the circuit? Speaking of which, when one says "overload the circuit" (ie: don't plug 20 strands of xmas lights into one circuit), is that "circuit" referring to plugging way too much into a *single outlet* in a room, or to the entire circuit that powers all outlets in a room? Example: Is plugging 2 strands of xmas lights into 10 outlets in a room just as bad as plugging 20 strands of lights into a single outlet? I'm starting to make a list of all the power supplies in the room and what I probably expect to have to see what my total volts/amps/watts usage would be. If any further info needed to help me figure out, let me know. Thanks!
