1st post so go easy :-) and hoping someone can help. I am currently investigating the feasibility of this and whether to approach an electrician on it (i.e. is it even possible without massive rework).
I have a 100Amp main panel which has a 30Amp breaker connected to a sub panel in another part of the basement. Wiring etc. all looks good and right gauge.
The sub panel used to power a small workshop but I want to add a laundry room in the basement. Additionally there is no dedicated oven circuit and as this sub panel is closest to the kitchen (underneath) I would like to run an oven circuit. All in then this equates to:
- Lights: 15A
- Outlets: 15A
- Washing Machine and Dryer: 20A (it's a gas dryer currently but I would like to add future support for an electric dryer (30A)
- Oven: 30/40/50(?)A
- Electric Dryer (Optional!): 30A
From what I've researched this would be too much for the sub panel (if all items where on at once) as it's only a 30 amp panel. Is this right?
I my pretty sure the sub panel lights and outlets (which service a small area of the basement only) can be wired to the existing basement lights and outlet circuits which could reduce it by 2 x 15A (I think this small section was wired this way to prevent ceiling tracking. Would this make it more feasible?)

The plot thickens lol (im ditching the oven circuit for now for ease of understanding but will likely look at full upgrade anyway)
So turns out in the sub panel off the main panel there is a cable for the dishwasher and washing machine already! So i figured as the washing machine one goes over the same area of the basement i want to move the laundry room too i could pull it down and use it but now it gets odd. It seems like (from my research) this is wired as a split phase shared neutral (as per here: Term to describe two circuits run through one /3 cable) and in the receptacle i can see an entry and exit wire so i assume the exit wire goes off to the dishwasher. The wiring in the panel is odd. There seems to be 2 double pole breakers, one is 15A/15A the other is 15A/20A! The wires are split between them. Is there any easy way these can be split back to single dedicated lines? (excuse my horrific diagram)
