Thanks FC.

Is the rated wattage (listed on each device) the "peak wattage"?

I know the typical lights/outlets split. What I am wondering is whether
there is any logic to whether/how my *outlets* should be split. For
instance, one of my laser printers is 11A, and another is 7.8A. (Per the
markings on the device.) Should I divide outlets logically into 20A
groupings?

Thanks again

(snip) I have never added a breaker, but as I see it - as long as I turn
off the main breaker, avoid the supply lines, and properly size the
circuits, I should be fine. (The house is about 30 years old. Box is
200A. I assume the electric service to be original.)

Q#1. Are my assumptions correct?
Q#2. How should I split the circuits?
Q#3. How do I go about sizing (amperage) the circuits?

Thanks!

Q1. If you're far from the limit of your power supply then you're probably
fine.
Q2. It depends, if your house has anything close to modern electrical
panel then you can just plug in the circuit breaker (if there are empty
slots). Otherwise, I'd call in an electrician.
Q3. by the formula I=P/V, add all the peak wattage together then divide it
by 110 to get your amperage. Make sure you have some room to spare.

Usually there is only one circuit for the entire basement. I'd suggest put
your outlets on a different circuit and connect your lights on the
original circuit.
