We rewired a swimming pool pump room for a local summer camp. We had a short piece of solid #8 to connect our equipment to for bonding and creating the equipotential bond. We had about 10 pieces of equipment to bond.
My Buncombe County inspectors told me I had to connect to the #8 with an irreversible connection and then run a continuous #8 to all the equipment.
I thought this was excessive and started researching what the 2017 NEC Article 680 had to say about the matter.
I found the term irreversible is used twice in the 2017 NEC. Both times referring to grounding electrode conductors, not bonding or grounding conductors. The two uses are: Article 250, Part III, 250.64 and Article 250, Part III 250.68.
I found Article 680.6 Grounding, states that the grounding has be done accordance of Article 250, Parts V, VI, and VII. Both uses of irreversible are in 250 Part III so the irreversible connection does not apply.
Looking further into article 680 and we find that 680.26 (B) states “Connections to bonded parts shall be made in accordance with 250.8”
Based on my assumption that a split bolt is a pressure connector, I decide to use a common split bolt that is listed for grounding and bonding.
I wanted to make sure a split bolt is a “pressure connector” per 250.8 (A) (3)
I looked in article 100 and found the definition of pressure connectors.
