Distribution box grounding to lightning protection strip
26 mm 2 (10 AWG) ground wire must be used, and in all other markets a 6 mm 2 must be used. On the US market, a 5. ected to shield it from lightning. It is located at an elevation such that a line passing through the static wire and the outermost conductor below it is at a 30° aximum angle with a vertical line. The static. Today, we're diving deep into the world of distribution box grounding, breaking down the standards, and shining a light on those sneaky mistakes that even experienced electricians sometimes make. We're your complete source for grounding and lightning protection components, including coaxial lightning protectors, coax shield grounding kits, copper grounding straps, grounding plates and. The need to electrically connect the grounding loop of lightning protection installed directly on the building with the grounding loop for electrical installations is described in the current regulatory documents (electrical installation code). While it is desirable to use the configuration that offers the lowest dynamic resistance, it is not simply a matter of picking one configuration and using it in every.
