comment What is involved in DIY swimming pool maintenance?
Just a nitpick: you probably mean hypochlorite. Chlorites (and perhaps also chlorates and for that matter perchlorates) also kill stuff, but the stuff I get at locally is definitely hypochlorite. And yeah, I've had a burst strainer basket or two exactly as you describe. The wages of sin (laziness).

comment Is an ungrounded GFCI outlet safer than a plumbing-grounded non-GFCI outlet?
Not sure I understand... I'm sticking to the brief of the question: choose the lesser of two evils.

comment How important is circuit breaker breaking capacity?
Typically the Prospective Short Circuit Current is governed by your supply, not the circuit downstream of the breaker. (Think of it like this: a very short but otherwise normal circuit would be as "overrated" as a longer one using thicker wire. The breaker has to work regardless of where the short is.) The governing PSCC may be vastly greater than what your worst short could practically pull due to distance from substation etc. Local codes will say what minimum PSCC to assume.

comment Amp rating of ganged circuit-breakers
Adding to what @shirlockhomes mentioned: circuit breakers are not like resistors that you can put in parallel to achieve a higher current carrying capacity. Instead, the one with the poorest connections will hog almost all the current, and then trip, and pass the current along to the next-poorest-connected one, where the process will repeat. Unless you're lucky and they happen to share nicely, you'll end up with just an expensive under-rated breaker.
