Lightning Grounding and Bonding
Lightning Grounding and Bonding
(OP)
Around 10 photovoltaic solar panels fixed on AL structure is installed ground loop. Another ground loop is 100ft away around control house where are installed AC and DC O/C and surge protection.
These two loops are connected with two conductors creating third loop.
My manager is suggesting :
1. Connect to the first ground loop two lightning rods
2. Connect to the same ground loop - common bonding bus where are connected (a) metal supports of solar panels (b) metal PV solar frames (c) metal protection boxes ( for surge protective devices).
3. Create another common bonding bus at control house where are coonected main surge protective devices
Can I mix lightning protection and bonding on that way. Can I create a common point for solar panel metal supports and SPD - surge protection device metal boxes before I go to the grounding.
My answar is NOT. Maybe I am wrong

chapter 4.13 and 4.14.
4.14 Common Grounding.
4.14.1 General. All grounding media and buried metallic conductors that can assist in providing a path for lightning currents in or on a structure shall be interconnected to provide a common ground potential.
4.14.1.1 This interconnection shall include lightning protection, electric service, communications, and antenna system grounds, as well as underground metallic piping systems.
