Can I use a dryer circuit to feed a sub-panel and the dryer?
No!
You said in a comment that this scheme is to power a shed.
Most dryers use about 6kW. With the dryer running you can't use any one thing over 600 Watts in the shed and not more than 1200W total. …

I want to add a subpanel that is supplied by multiple hots
If you are limited by your landlord to 10 x 120V 20A circuits, and if the goal is isolation so you can safely work on the wiring in your space, you can achieve that by running the ten circuits through …

Is 12/2 cable to subpanel ok?
If everything is protected by a single 20A breaker in the main panel and if that is adequate, why not just repurpose the garage fuse box as a junction box? Strip out all the innards and replace with …

Does my panel have space for a double breaker?
It looks like you could easily move breaker 7 to position 6 and breaker 9 to position 5, freeing up a slot at positions 7 and 9.
You might have some unlabeled and untied MWBCs. If so be careful not to …

How to bring 1/0 wire through foundation below grade?
It looks like you could use a fitting saver in the horizontal opening to cut a hole in the side of the vertical pipe. But it would be very difficult to pull 1/0 wires through that. I don't have the …

Wiring 2 generators and utilizing a subpanel
Assuming the subpanel is on the main house and does not have its own ground bond, both generators need to be unbonded and both need ground and neutral attached separately to their respective panels. … If the A/C blower breaker is in the main panel and the sub generator can cope with both the compressor and blower, it would make sense to move the blower breaker to the subpanel. …

Can a fuse panel supporting knob-and-tube wiring be replaced without a new feed or updated c...
In this box you'd splice everything, carefully to new cables that go to a new subpanel nearby with its own new feed. … I think you could probably (hopefully) feed that whole subpanel with a two-pole 20A AFCI breaker and then use 10A breakers for all these circuits. …

Is a double 30 amp breaker powering three rooms bad?
Note: This answer pertains to an earlier version of the question when the small fuse panel was undiscovered and OP thought the rooms were all directly on a 30A breaker. While that does not turn out t …

How can I add a neutral to a 240V to 120V circuit conversion?
If everything (there is only one thing) on this subpanel is 120V, install a separate neutral bus bar and use the unused feeder as neutral. Leave the grounds the way they are. …

Proper way to extend circuits to subpanel
Using the existing big conduit is cheapest and easiest. A couple of 50 ft reels of wire (black and white) and a box of wagos and a couple of hours. It leaves the left panel a bit crowded with wires …

Can a circuit connecting to an outlet be branched as a subpanel?
There is no useful combination of breaker/outlet/subpanel that could work this way.
You can't run say a 60A subpanel off a 60A breaker and put a 20A outlet on the feeder cable. … Then, if it's allowed you could continue to a 50A subpanel. (I don't think that's allowed anyway). …

Sub Panel Power Loss While Feeder Breaker From Main Still Has Voltage
Some ideas:
Confirm 240V between the two terminals of the 100A breaker when on, 120V between either one and neutral, 0V between the subpanel feed terminals and 0V between either of them and neutral. …

NM-B wire/ampacity for subpanel - NEC 310.16 and 334.80
(Well the other thing wrong with it is that it is penny-wise. 100A aluminum cable and a 100A breaker would make the subpanel more future-proof. But that's up to you). …
