New rules for Type SJ in 2020 NEC

Why aren't you installing a 5-20R instead?

North of Little Donnie's Walls, in residences, our utility branch circuits are typically breakered at 15 Amps to protect 14 gauge copper wiring.
Toodleoo!

Thanks, but does bring up the question of in avoved... say a 5' jumper between pipes in a fly system... is the copper strionger between such a 5' connection in difference between SJ and SO cable? Certainly the rubber isn't stronger in possible tension.
But as long as it's on a 20 amp breaker... the SO cableis only ok? Because it's in the air.. so a scrim might hit it?
And by the way, I very much appreciate your time, help and guidance. Just asking questions.

Well, one reason we have different codes, even from province to province, is related to geography. Grounding, trenching, insulation, and such tend to vary depending on terrain, climate, proximity to seawater, etc. Codes tend to get tweaked to suit the things the local inspectors care about. Now let's debate the proper orientation of a NEMA 5-15R.

Very sorry in advance, but...that is simply horseshit.

It is nothing more than another unsupported rationale for multiple Codes where one well-written one could do the job. Likewise, one North American electrical code would do the job for both the US and Canada if we just tried.

Neutral is always up if horizontal. Same reason as ground up.
