Getting ready to put in a ceiling heater going to be using a 220v plug outlet on it's own circuit so before it gets here was looking over my breaker box, making sure my 220v circuit had the right size wire etc...noticed I don't have anything labeled...so...spent the day checking each breaker to label it. I thought I had every thing spread out pretty good, because you know saws and what not pull some heavy amps some times. Every thing was pretty good except one circuit...I was shocked... seems when I use my CSMS, man I got a bunch of stuff running on that circuit, when I use it that circuit it has a mini frig (2.4 cf Kenmore) plus my Dust collector, and because it's my CSMS my shop vac (csms needs both Shopvac and DC) and the CSMS itself, they are all on different plugs which is why I assumed I was spreading out the load. How is that possible to run all of that on one 20amp breaker, jeez the csms is 15 amps and the DC is also 20 amps, that alone should kill the breaker. The DC always run with every machine, but the CSMS is the only one on the same circuit with the DC. The mini frig is always on with the DC, can't change that, the shop vac I guess can be used with an extension cord to the other side of the shop. But for some reason I use this setup all the time, never had a breaker trip, can some one explain how I run four major pieces of equipment on one 20amp breaker. Granted I turn on things one at a time, but still, that's a lot of stuff.
edit: did a quick check...that's 42+ amps on a 20 amp breaker
HF Dust collector - 20 amps
Kenmore mini frig - 4 amps (guess couldn't find a plate)
Shopvac 16 gal - 7.4 amps
Dewalt DW717 - 15 amps
