This page will help if you don’t want to mess with or know the formulas.http://www.jobsite-generators.com/power_calculators.htmlSo what I use is this:watts=amps X voltsif this is the case then w/a=vw/v=aso to use this in a project I’m currently working on I have 6 puck lights at 20watts each so I have a total of 120 watts in lights I also am installing a plug in this wet bar. So since this is a wet bar I figure the highest power usage item is a blender so I looked when in Lowe’s one day and the largest power consumer(blender) they had was at 650watts so I said to myself okay lets use the formula.650w + 120w= 770wso everything is standard kitchen wiring so it will be 120 volt(110V) power supplied.770w/120v=6.416 ampsokay so I like to round up and play on the safe side when it comes to electricityso 7amps well knowing this I know I can use 14/2 wire(Romex) but being the safe person I am I’m using 12/2wire reason being is I don’t know if some jack-leg is going to plug a power strip in here and try and run 3 or 4 blenders when he throws a party showing off is new wet bar. I would rather throw a breaker than burn down a house.O by the way 14/2 “UP TO” 15amps at 120volts12/2 20amps at 120volts it pretty easy once you now what you are working withwhen you talk about 220 your amps start to drop but what most of you guys are talking about are machinery motors which have a huge start-up draw.What I did in my shop was to run your lights on a completely different circuit not hard to do just find an open spot in your breaker box and place a breaker and put all your lights on this breaker I then have plugs for certain machines watch your plug buying they are amp rated also so everything should be rated for more amps than you need and every thing should have the right size wire for the amps your are carrying(this is where fires happen to small of a wire for the amps being pulled) allows play it safe and if you are the least bit unsure than find someone that knows because there is no room for maybes.Our tools will definitely burn up if they are not supplied with the proper amps and amps are lost in connections and distance okay tired of typing hope this helps -- Wood,clay,metal, and stone are all just materials, until an artist's hand touches them.--TreeFormDesign
