I recently saw a boat hauled out that had hot-pink propellers and shaft nuts. There were no zincs left, and the pink was a sure sign of a “hot boat.” It reminded me of an incident we had years ago on ...
How to select the proper neutral-grounding resistor for a high-resistance grounded electrical system
High-resistance grounding (HRG) makes a power distribution system safer and more reliable than the alternatives. High-rresistance grounding can limit point-of-fault damage, eliminate transient ...
A separately derived system (SDS) has no direct connection to other sources except through grounding and bonding. Grounding and bonding must be performed at the source, not on the load side, to ...
Article 250 of the National Electrical Code (NEC) focuses on grounding and bonding. This Code Article is divided into 10 separate parts — each identified by a Roman numeral. Because of the terminology ...
Recently we got our hands on a Hyper Ground electrical grounding system from Sun Overseas Trading. The system, composed of heavy-gauge, 99.99 percent pure copper wires provides a low resistance ground ...
