Homerun (electrical) soil stack (plumbing)

could someone explain what a “homerun” is in electrical design?

also, could someone explain what a “soil stack” is versus a vent stack in plumbing design?

thank you!

Hi @wildlandguy -

Homeruns are simply wiring from a circuit back to the electrical panel. They’re typically not shown in architectural RCPs, but are shown on drawings by electrical engineers, since they design the circuits/panels for a project. I would say that homeruns are more of a means and method item and you don’t need to know any more about them than the above for the purposes of the ARE. To learn more about what you should know about electricity in general for the ARE, check out three of our videos - our PDD video course has a video titled ‘Electrical’, and there are two PPD videos titled ‘Building Systems - Electricity’ and ‘Electricity - Impact on Design’.

Our PPD video ‘Waste and Vent Riser Diagram’ does a great job of answering your second question, check it out!

Thank you Chris. One follow up, on a homerun, is there only 1 receptacle exclusively wired to the circuit? Or can a homerun have multiple receptacles on it?

Thank you

Homeruns generally have more than one receptacle wired to them - for example, you might have all of the receptacles in your living room on one homerun back to the breaker panel.

Your clothes dryer, however, will have its own homerun back to the breaker panel because that’s on a dedicated circuit.

Hope that makes sense!

yes, it does. thank you.
