I also heard that the change(TIA)was implemented due to the end cost to the consumer. Why would a change in a code rule be made because of cost?
Cost is always a consideration when it comes to any rules.
We would all like to say save a life at any cost but in reality that is not what we as a society do.
40,000 people a year are killed in cars, they could be made safer than they are now but they would not sell.
All things come down to a cost vs benefit decision.
If the equipotential bonding grid is necessary for safely masking stray voltage around a pool to protect persons using the pool, then IMO, it should be installed...
Maybe that is part of it also.Is
the equipotential bonding grid necessary and / or effective?
A whole lot of pools have been installed without this grid.
Is there a history of problems with these installations?
I don't know the answer but judging from past MEC practices they are not quick to implement new rules.
