Need to understand

[John Adams]

Please bear in mind I'm a telecomm guy and NOT an electrician or EE. Here's my question to all of you
My interpretation of Article 250.94 is that a intersystem bonding busbar must be placed on all new construction. If that's true, why do I never see these installed on any new military building? We're still installing a #6 from our busbar (now called a Primary or Secondary Busbar) to your Main Panel or sub panel. Then you guys hook that up to your busbar within the panel. The question I get is "where's my intersystem bonding busbar?" for which I have no answer
help please!!!

As far as I can tell it is the electricians job to supply the intersystem bond. If that is not done then it is because the inspectors are not enforcing it. If the military is using the NEC then they are at fault and should be aware of it. Show them the code section and see what happens or better talk to the business owner.

The navy, army and air force bases I have taught classes at typically don’t have permits, inspections, or require licensed electricians. Since they are under OSHA, they are using the latest NEC.

From what you guys have stated, I am right on enforcing the placement of the intersystem bonding busbar. That makes me feel a little better. The bad news for the electricians is they aren't required at all in this scenario. The telecomm guys can now place their busbar (PBB), run the #6, and terminate it on the intersystem busbar. In the past, the electricians were hired to do that whole process. THANKS for the help
