I purchased a 14KW Generac standby generator 2 months ago and had an electrician do all the connections from the generator outside to the transfer switch inside and to my main circuit breaker. As this is my first generator, I had naively assumed that the electrician would do the complete installation. He explained before starting the job that he cannot do the propane hookup as he is not licensed to. I had assumed this would be a trivial thing that I could either do myself or get a local plumber to do. Over the past two weeks I discovered that only my propane company (Suburban) would be able to do the job, and they charge $490 for it. Does this sound right? I would think that they only need to put in a T-connection, a 10' hose and an in-line regulator to do the job. Seems like extortion for something that looks like it take half an hour to do, tops. Am I wrong? The field tech who would do the job explained that they need to charge this to insure the job. Furthermore, he explained that the electrician needs to be present during the hookup and run the generator. Since that conversation over a week ago I've been trying to contact that tech to schedule a time that he and the electrician can be there, but the tech has been totally unresponsive, not returning calls and messages I've been leaving for several days now. Anyone have advice for an alternative, or do I have no choice but to deal with the expensive hookup and poor responsiveness from Suburban? Thanks!

I'm trying to properly bond a length of flexible propane tube. A 500 gallon tank is buried 50' from home, iron pipe then it enters the basement. It runs essentially the length of the basement where it re-emerges outside at the standby generator, which is located very near the entrance panel, meter, and GEC/rods. The code calls for #6 min. attached near building penetration, going to bonding system. Would it be reasonable to bond the end nearest the service entrance? Exact wording of the code references downstream of the meter and doesn't describe the case where the CSST enters a building and then exits the same building.
