Service Mast height requirements

[JFrito51]

What is the height requirement for the mast above the roof for 2" Conduit? The conduit punches through the overhang and out through the roof.

To many variables for a straight forward answer.

There is a minimum height to bottom of drip loop, also depends on how the drop crosses the roof. In WA we have very clear state rule on service mast height. As pointed out , some variables, and you didn’t mention voltage. Suggest reviewing rules in Art 230

A lot has to do with what's under the wire

Look at 230.24.
as others said..too many variables.. voltage, roof pitch, distance to edge, ect.
Plus many POCOs have their own rules.

And even if you meet all of the NEC requirements, you still need to check with the utility as to the height they need at the attachment point so they can maintain the required height of the conductor span between their pole and the service mast.

As has been said, check with your POCO. Here, if we penetrate the roof, we must use 2-1/2" rigid. If we go a certain height above the roof we have to brace or guy it. The height is POCO dictated. Some start at 36", some at 42" above roof.
