My understanding is it depends on the local code. I know many older homes have the service drop attached directly to the house, but you said this was a newer home.


The main issue I could see is the service might night meet the NEC rules for clearance.

Not at all, consider underground service.

Overhead service requires specific clearances from the ground and structure at the service drop and the "service point." That is the where the service mast (riser) comes in.

In your picture, there appears to be a problem with the required clearances - from the ground and window - so I would say there should be some other means of creating the service point whether it be a riser or lateral (underground service).

Are you saying that type SE cables do not require the specified clearences? Is type SE supplied by the utility company for the service drop?

Jeff: I was just stating that the SE cable can be used in lieu of a mast. It still has to meet clearances unless it is under the exclusive control of an electic utility, as per 90.2(B)

Thank you all so much for your feed back. I’ve learned something here.


Also, looking at my photo, which I attempted to resize. I can see that I distorted it somewhat and it "appears" that the line is less then 10 ft. heigth clearance. It really is above the required minimum. My only concern was the lack of the service mast.

To clarify, this is not a new house. Actually, it's almost 100 years old. But it was remodeled about 5-6 years ago with new siding, among other things.

Thanks again

Unfortunately, many utility companies will hook up to whatever the customer supplies.

Larry -


As most of the guys know - in older houses the masthead was not always used. In my area of Kansas City, many houses over 30 years old, had no masthead. If this house was recently remodeled and any electrical UPGRADES were done, it makes you wonder if permits were pulled, etc.

Another dump question…


Is that service drop too close to the window?

Souk’,


It's hard to tell with the distorted picture but the NEC requires 3' clearance from the sides and bottom of an openable window.

It looks too close to me.

I measured at approx. 3’6". So I’m OK there.


It doesn't appear there was an actual upgrade on the electrical, but I wonder how they got the new siding on.

I never saw a service mast until I moved to Florida. All the houses I ever saw in Maryland were 2 story and had the drop connected to the roof line somewhere, like this picture. They tacked SE cable down the wall to the meter and into the house.
