> GFCI receptacles have been required in many locations by code going on four decades Yeah but receptacles protect the user of the circuit, not the circuit itself / someone working on it. Plus you’re not protected on all the circuits where it’s not required by code. One RCD at the main is a lot smarter and more cost effective. Not to mention easier to mandate retrofits for, whereas somehow we’ve accepted in the US that tons of kids live in houses where there’s both no GFCI in the outlets in their room and no tamper resistant devices, it’s ridiculous. > The cost is dramatically lower for wire nuts and GFCI receptacles than for GFCI/RCD breakers and lever nuts. I just picked up a ten pack of Wago lever nuts at Home Depot for $7 – Grainger/Zoro recently stopped carrying Wagos Yeah you’re saving 0.2-0.3$ a pop (they cost around 0.4$ a pop if you buy them online by the 50s, I assume supply houses are cheaper) at the cost of much more time spent twisting, time troubleshooting later and worse health from having to twist those wire nuts for your entire career. > If anything I'd say that there's regulatory capture from the manufacturers, take a look at the price of a breaker with an arc fault interrupter Main breaker RCD is obviously the cost effective option :)
