I have seen it done. As i recall at the time, the gasman had NFPA 54 ( i think), and asked for a separation of 12" in the ditch.

so i guess i'm a "uh-huh"

Wirenuts, looks like you have the handle on it, I agree.

However, don't forget to install the warning ribbon above them in the trench.

Thumbs up

And this warning ribbon would be ?

I take it just to remind myself and to let someone else know whats in the ditch also.

So I guess its a go.

Thanks guys !

The following requirement was added in the 99 NEC. Be aware that this only pertains to service laterals that are not fused. If just an underground feeder or branch circuit then this requirement does not apply because they are protected by an overcurrent device such as a breaker or fuse where a service lateral is not protected by a breaker of fuse.

300-5
Service laterals that are not encased in concrete and that are buried 18 in. (457 mm) or more below grade shall have their location identified by a warning ribbon that is placed in the trench at least 12 in. (305 mm) above the underground installation

good luck

My Two Cents

Hello Gentlemen

The question has been asked in the other forum and I posted my reply. To save you all the time looking elsewhere, yes, joint trenching is very commonly done. This is especially true in newly built housing tracks.

I would also suggest that you check with your local utility (gas supplier/electric supplier) as well as your local building official. My local utilities have no problems with this, but one building authority does not allow it.

Enjoy your day!
