I am trying to complete a 100-200amp upgrade on my home (final hook-up to be done by the utility company).

My question is about the Service/Weather head mounting. The service cable runs at an angle up the roof line of a cape code style house - where it will connect to the main service line. Can anyone see a problem mounting the service head at an angle as shown in the picture? They're obviously designed to be mounted vertically for maximum weather protection...

Thanks very much

BTW, the wire shown in the picture is a scrap piece, the length of wire from the head will be greater.

That's done all the time. Remember to leave enough wire for a drip loop. That's what's really protecting the conductors.

Let me add, a Service Entrance cable weather head like the one shown in the photo, is rated rain tight only when mounted so the top of the cap is horizontal.

However, it can be mounted on an angle if the inside of the cap is filled with a putty. We often use Duct Seal, a band name for a moldable putty used by electricians.

Spray expanding foam, Great Foam, is also used.

Many inspectors require the cap to be filled even when it is mounted horizontal, as SE cable is popular for allowing water to seep in and travel down into the meter by capillary action.

Regarding the drip loop,I have to assume the photo is only a mockup. Code requires a min of 36 inch tail on all the wires, allowing the utility lineman enough wire to form a drip loop. Check with your utility as many have their own requirements for length of wire out of the weatherhead.

Even with a proper drip loop, without filling the weatherhead, water will still seep in.
