Mast Service Conduits

Can the mast service conductor horizontal section have a slope like in picture? If water got in through the entrance cap or an improper drip loop, it would collect inside the conductor. I suspect that the brackets got loose and the mast slid down.


I don’t see a concern. It looks like the weather heads are in good shape with a proper drip loop.

It can (as shown in your pic) :wink: But jokes aside, per your observations, the drip loop looks good and the caps are under the soffit (aside from wind-driven rain) protected from rain and look ok from here. A loose mast would concern me more than water in the conduit in this scenario. Does the service entrance meet clearance requirements to the ground/driveway? Both of them with the same slope seems like it was installed like that :man_shrugging:

Could recommend a drain hole at the elbow, lol.

I agree with Lon though. Very little concern. You could recommend it be repositioned for aesthetics. I would recommend positioning a clamp immediately below the masthead where there appears to be a lip that can rest on the clamp and keep the whole thing from sliding down.

And technically, If that is a telecommunications box to the lower right, I don’t think that should be attached to the “mast.” But not sure where we consider the mast ending and just plain conduit beginning.

Neither do I until there is…

It looked good.

It would look more professional if repositioned; I like the clamp to prevent the conduit from sliding down!

A clamp on the horizontal near the bend would have a better mechanical connection, not rely as much on friction.

I would probably call it out for correction.

Exactly, that is what I was thinking of.

Yes, I did.

The issue is that they didn’t properly support the horizontal portion of the run within 3’ of the conduit body as required so the PVC slid down. The result is a raceway that is not designed to properly drain. IMO with two code violations it needs to be fixed.

352.30(A) Securely Fastened. PVC conduit shall be securely fastened within 900 mm (3 ft) of each outlet box, junction box, device box, conduit body, or other conduit termination. Conduit listed for securing at other than 900 mm (3 ft) shall be permitted to be installed in accordance with the listing.

225.22 Raceways on Exterior Surfaces of Buildings or Other Structures.
Raceways on exteriors of buildings or other structures shall be arranged to drain and shall be listed or approved for use in wet locations.

Those were my thoughts also, thanks Robert and everyone that responded!

Why are there two sets of service conductors and where do they go? Is that a two-family building? Do the conductors pass through the wall and terminate in two separate meter sockets on the inside wall? I normally expect to see one set of service conductors and a dual meter housing in twin-plexes and duplexes. I don’t think I have ever seen a setup like this.

Marcel,
Any idea what was on the inside? It looks like parallel service raceways to a CT cabinet on the inside. I see the small meter which may indicate a CT metered service.

That sounds about right Robert!
4,000+ sq. ft. single family house with electric heating and 400 amp service disconnect as per label on cabinet and a CT. I could not confirm as the cabinets were sealed by the utility. There was a 200 amp distribution panel which was full; owner commented that they were planning on adding another 200 amp distribution panel for a planned hobby farm barn.
