Hello all. I'm finishing part of my basement and making it a workshop. Because of all the new circuits I need, I'm quickly running out of space for new breakers. I'm thinking I need to add a sub panel (it would be right next the current one). I noticed that my main panel is only 150-Amps (I know, it's unusual... part number TM3215CCU). I attached a picture of what breakers are currently installed. These were all installed by the builder in 2003 when the house was built.
I there an easy way, or rule of thumb I can use to determine how large of a sub-panel I could install? Right now, I'd like to add four circuits for the workshop (one 15-amp for lights, three 20-amp for tools) plus one additional 20-amp circuit to add to the existing finished area since the previous owner did a DIY job and only put one outlet in the entire finished basement :-( I also have future plans (dreams?) to add a hot tub, which will require its own sub panel outside (I did this once before on a previous house but there was plenty of capacity to spare in the main panel, so it was easy).
Thanks in advance for any advice you have to share!
