Can I run 3 circuits to a shed 15 feet away through conduit, or do I need to install another sub panel?

I just had a 100 AMP sub panel put in my shed by a pro. Now I want to run 3 circuits to my other shed 15 feet away. Can I run those circuits through conduit, or should I get another sub panel installed?
Why share that tip? A 1/2″ conduit is legally capable of carrying the permitted circuits.

Yes, you can. However, it’s not up to code if you’re planning to get it inspected. It should be in NEC 225.30 for feeders. You should only have 1 circuit running to a shed… at least that’s what I believe. But I’m open to differing opinions from others in this group.
Yup, that’s right! In this situation, multiwire circuits are considered as a single circuit, allowing you to run 2-120v circuits with one neutral and a 2-pole breaker.
The issue, as Jack iblin pointed out, is that he wants to have 3 circuits connected to the shed. In this scenario, those 3 circuits running at 120v each cannot share a common neutral
I’m not quite sure how that system works now, Jack iblin. Where I am, they’ve made everything be protected by FCI at the panel. I used to wire my small appliance circuits differently, but now I have to run 2 separate lines because the FCI breaker keeps tripping

O ahead and run them…

Make sure to run them, but also consider adding a disconnect in the line for the new shed

Yes, you can use the right wire, like THHN and THWN. x wire won’t work, it depends on the breaker sizes.

Definitely run them off the sub panel, there’s plenty of space. Just make sure to consider voltage drop over the distance and size of the circuit you’re setting up, especially if it’s a long run.

Yes, but it’s better to install another panel for easier access

Try stabbing a 60 in and wiring 4 to another one

I assume you’re referring to a separate conduit from the panel you shared a picture of. Absolutely, that makes sense. Running wire through the feeder conduit wouldn’t be practical.
Hey , what’s on your mind about powering up the other shed? What are you looking to have in there?

You don’t necessarily need another panel. It’s really up to you if you want it or not. If you’re just going to power receptacles or lights in the shed 15 feet away, or even a welder, you don’t have to add another panel. Just keep in mind to use conduit for your phone wires. And please, avoid using x. Pull the wire through and glue it all together, it’s the safest way to do it.

If you want three circuits, you’ll have to set up feeders to another subpanel in the other shed to meet code requirements.

No. A separate building can only have one circuit running to it. You will need to install a disconnect of some sort in the new shed no matter how many circuits you plan to have. If you can handle everything with just one circuit, then you’re all good. Not sure what you’re planning to power though.

Definitely not, not even for oogle haha. Running a 2 pole circuit seems possible, with a shared neutral, providing more options depending on your needs. LED lights and some receptacles would be a good fit for this setup, but if you also need heat and 3 circuits, better go with a small panel that includes a main disconnect for the building – unlike the panel in the picture. There must be a breaker, switch, or any form of disconnect that can cut off power to the entire building, either on or in the building. The one in your house panel doesn’t qualify, so unless there’s a separate disconnect for this building, the installation was done incorrectly

One circuit to a shed without an additional load center and grounding electrode. However, if what you’re running is relatively balanced loads you can run a multi wire branch circuit double pole 30A feeding your receptacles with one neutral. If balanced well you could load each leg with nearly 30A worth of 120v stuff

Install a 20A outlet on a 20A breaker. Then use a 12/3 cord to temporarily power over. Once you’re done, roll it up and hang it back in the shed with the sub panel.
Sure, just run it from there. Just make sure the conduit is large enough for the circuits you’re running

You’re right, . The feeder conduit is not the correct choice
