Situation boss wants. Revamping an old communication tower and building. The gen set will be installed inside the comm. building but I have a pad to pour out side for the lp gas tank. The tank will be located about 12ft from the building. The gas line I will install is plastic. The risers are metal above ground then transition to plastic with the stab locks for the pipe. When I come into building I will run black pipe to the gen set and connect with a flex hose provided with gen set. Gen. set will be of course bonded with EGC. What boss wants to do is run an EGC to the gas tank, install a lug on one of the legs and tie the EGC back into the halo grounding system for the building. Unsure on this. There will be no metallic connection between the tank and building and if/when the system takes a hit could it cause or be more dangerous to have the EGC on the tank?

What type of flex hose? If it's CSST the bond needs to be on the black iron pipe. THE EGC is not a suitable bond, nor is running an extra one to the tank. You need a minimum #6 copper
 
If the tower is to remain, I would bond the tank. If the tower is removed and the site has lightning exposure, I would bond the tank. There may be a requirement for bonding in some fuel code that I don't have.

Yes, tower will remain. We will be using the tower and building for our equipment.

It is not csst flex but any thing metallic in the building is tied back into the halo. We use #2 for all panels and cabinets #6 for all conduit, door frames and such. The wire I will run to the tank will be #2 hard drawn bare copper

Since it's not CSST, the EGC would be enough to bond the piping. The extra bond is not required, but would not hurt anything.
 
Ceb,

I would go with bonding the tank to the 'halo', just like all the other metal objects around

it. jmo.

FWIW, There is a new 'lightning' documentary on the Sience Channel this week. It shows

lightning @ 7000 frames per second and reveals x-rays and gamma rays not seen before.
