Electrical circuit question
Lets say I'm planning a rec room with 3 TVs (each with cable boxes) - some extras like Roku, BD Player, and of course charging of phones. Where would I start to see how close I am to being over loaded?
I get looking up the specs of the TVs, boxes, etc but I get confused with the Watts/Volts/Amps conversion.
Any direction or help is appreciated.
