Another newbie question

[poeboy]

With respect to DB or not....

• 1) I'd rather use a conduit, but if the customer likes the price of DB better, then give the customer what they want.
  
• 2) If the ground is rocky or somehow may be harmful to the DB wiring, then conduit is the only answer, but the question then becomes PVC, IMC, or RMC??

I personally like IMC cuz it only needs to go down 6 inches..or PVC cuz it is reasonably impervious to nearly everything except a shovel, or plumbers looking for the drain field...... :grin: even with a trencher going down knee deep for PVC is not the highlight of my career.... :roll:

Anybody else have an issue with direct burial cable?

If you have burrowing rodents in the area of the installation your customer can't afford to not have it installed in a raceway.

I have repaired rodent damaged conductors that were buried 5 foot deep before.

I have also heard that minimum raceway size for non metallic raceways is 1 1/4 inch otherwise there are some critters out there that will chew through the raceway too, although I have not seen it myself.
