grounding of the mats and supporting structure grounding of the lead-in wire to an antenna-discharge unit, size of

the grounding electrode. See Figure below.

shall be connected to the grounding system of the building, as close to the point of cable entry as practical.
Objects and Liquid Entry – Care should be taken so that objects do not fall and liquids are not spilled into the
enclosure through openings.
