As a leading expert on grounding and the NEC, Mike Holt has made it his purpose to keep people safe, and to teach electricians what to do to make sure that your pools, spas and hot tubs are safe to swim in. The risk associated with swimming pools is that of electric shock, due to a reduction of body resistance because a person is wet, and also the possibility that a person is in contact with earth potential. †
The Consumer Product Safety Commission reports that since 1990 there have been 60 electrocutions and nearly 50 serious electrical shocks involving electrical hazards in and around swimming pools.
