What up @hiboy, thanks for all your help on my previous questions, I hope you can help me with this one:
The main panel on the third floor is 63 amps (3x 10 amps, 1 for each floor, 1x 25 amps for oven, 1x 20 amps for the washing machine) and then I found out there's a small sub panel in the basement (just next to the bloom room) which has 3 breakers (washing maching and some other stuff) - Like I said in my post above I wanted to install a sub panel for the bloom room in the basement - Can I somehow use this already existing sub panel to do so?
