Sub Panel Question
Hi all,
I currently have a 100 amp service and the panel is full. I have no need to upgrade the service (!). I would like to add a sub panel, rather than replacing the current panel with a larger one.
My question is, is it possible to add a 100 amp sub panel? Or does the breaker feeding the subpanel need to be smaller than the main breaker?
Thanks!

A subpanel will increase your number of possible circuits, but it won't add one watt to your electrical capacity. A subpanel is not an alternative to a service upgrade.
It makes no sense to put a 100-amp subpanel off a 100-amp main panel. But you can put a 40-amp or 50-amp or 60-amp subpanel to give you more breaker slots.

Yes. Increasing the number of circuits is what I need to do. I do not need more than 100 amp service for my house (stated in earlier message), which is why I want to add a subpanel rather than replacing the current panel.
I was basically wondering how large a feed I can provide a subpanel. For example, if the main breaker panel is 100 amp, can you legally put a 100 amp feed to the sub, or does that breaker for the sub panel need to be smaller that the main breaker.
