How to Determine Which Conduit to Use for the Main Service
Question: Is there a maximum length that the line can be in the wall before it enters the panel?
I am installing a 200 amp service panel (semi- flush) in a 2 story residential house.
- The service is overhead and I’m using 2″ EMT conduit.
- My question: Is there a code problem here, since the service line is entering the building before is it fussed?
- Is there a max. length that the line can be in the wall before it enters the panel?
- Can I run the mast up through the second floor? etc..
- I will ask my inspector, but since they have Friday’s off (due to budget cuts) I was just look for some comments.

Thanks for your electrical question Tom.
Conduit Type for Home Electrical Service
- The type of conduit that is allowed in your area is determined by your locale building department and the electric utility company.
- In my area I can only install rigid steel conduit or IMC, however in other locations I have see Rigid PVC Conduit being used.
- As for the length of the approved conduit, there should not be a limitation as long as the length does not produce voltage drop.
