We have established that you cannot read for content. No, we do not install GFCI devices throughout the house. Where they are either necessary-by-code or just a good idea, we use the CIRCUIT BREAKER combination device. Then, it becomes that super-fast circuit-breaker.
I do not know if the higher-end devices have built-in snubbers - I do know that we are generally free of nuisance trips. As to motors, our hot-tubs ar e each fed with a 50A device that is about 30% larger than a standard doubl e-pole unit, and feeds to a common neutral- ending that myth. The pump is 1
20V, the blower is 120V, the heater is 240V @ 5,000 watts. So, depending on what is going at any given time, the load is simply not balanced.
All of our devices are damp-location rated, figuring it cannot hurt, and th e premium is minimal.
Kids, grandkids, cats, dogs, and all the parts-and-pieces thereto. Makes th ese sorts of choices pretty basic and pretty obvious.
