Is your concern grounding and safety from electrocution or are you concerned about lightning? You would use different approaches depending on your goal. If it makes you feel better Dade and Broward codes are a good deal more stringent than most of the rest of the USA.Keep in mind everyone's grounds are tied together. In addtion to grounding rods at each and every meter you have building steel and utility lines involved. For personal safety I encourage ground fault protection. For lightning, a panel mounted surge suppressor system is needed. In all instances, use high quality, high speed, self-diagnosing protective components. Transient limiting devices may use a combination of arc gap diverters-metal oxide varistor-silicon avalanche diode technologies. Hybrid devices, using a combination of these technologies, are preferred. Know your clamping voltage requirements. Confirm that your vendor's products have been tested to rigid ANSI/IEEE/ISO9000 test standards. Avoid low-priced, bargain products which proliferate the market (caveat emptor).
