Because splitting the lightning along many paths commences within the strike termination level and follows from the conductor system to floor, diverse resistance values of electrodes can upset this purpose. An in-floor loop solves this prospective challenge and provides an intensive wire community to improve the grounding program.
In terms of lightning and its stupendous Electricity, The underside line, suggests Willard, is usually that lights rods, when installed properly, supply a good route to floor for electrical Electricity, So mitigating or avoiding harm to properties.
