If the dish had been struck by lightening, our home would have blown up since the propane tank is only about 40 feet awayUm, no for several reasons, the main one being propane needs oxygen to ignite. A lightning strike alone will not make it ignite and blow up. The ground for your tank may actually be the best ground available. Any good earth ground should be at the same potential as your propane tank ground.
Every installer must present pictures of key areas of the installation.
I'm sure that the "official reps" are going to review the pictures of this installation.
Hughes is required to have installations conform to Federal, State and Local codes.
As to if the grounding method in the this case is "botched" or not will come out after a review of those pictures.
Speaking as someone who has built several houses I have to say that one of the most complex areas of the NEC (upon which most local codes are based) are the sections dealing with grounding and bonding.
From an installers point (and that of the NEC) is that all equipment be tied to a common point. That common point being the electrical equivalent of the service entrance ground point.
For all we know the ground wire at the propane is not to code.
Ground loops are to be avoided at all costs.
As to purpose of said ground, it is to bleed off any static voltage the may be induced. As "protection" against a direct lightning strike to either the tank, the dish or the structure .... forget it. That tiny ground wired would be the worlds most short lived fusible link in history from a direct hit.
Don't make assumptions. Wait for the picture review and the scope of Federal, State and Local codes.
I agree with you that better installer training is in order in many cases.
They (the bottom 50%) weed themselves out pretty quickly as a rule. I have always seen Hughes make right any substandard installations once its been noted.
We always hear about the bad installers but on the end of that argument is Alan of Eldorado Satellite and GoKartGo:
Remember, fully 50% of all Doctors graduated in the bottom half of their class.
Let the process work.
