Starlink grounding / Service Entrance Ground Distance

[jtarkington]

Mounting a Starlink panel on a 15ft mast that is 2.5ft from a home with no mast attachment to house. Looking at NEC 810 and other recent post, even though Starlink panel is plastic (of course electronics inside) and powered via POE with the CAT5/6 cable it still applies. Going to install an outdoor gas discharge surge protector on the CAT5/6 before it enters the home.

The challenge being faced is the service entrance ground is 60 ft from the mast. Looking at other posts, it appears that extending the service ground to the mast with the best approach being to install additional ground rods every 20 ft or less and interconnect with #6 or better to reach the mast.

Just want to check my interpretation of proper “extension” of the service ground to the mast.

Thanks,
Jeff

You don't need ground rods every 20 feet, just one close to the mast and then bond that to the building grounding system with a #6 of whatever length you need to reach it.

I agree. Sink the ground rod adjacent to the Starlink device and then run a bonding jumper to the building GES.

@infinity If the home currently has a intersytem bond couldn’t he just run a bonding jumper from the IBT to the starlink in accordance 810.21(f)(1)? It would be connected to the building GES and unless I’m mistaken I don’t think a seperate grounding electrode is required

The issue is the length. Take a look at 800.100(A)(4)Ex.

I completely forgot about the 20’ on the gec , thank you

Those sections are a little confusing because you have Article 800 requirements that pertain to several other articles.
