Couple questions about receptacles, circuits and TR requirements

[anythingyoucanimagine]

I understand nec2017 expanded TR requirements for 15/20a 120 and now 240v receptacles. I'm having a hard time finding duplex TR 6-20R. Did I screw myself? Should I install single L6-20R in each box vs. duplex non-locking?


30A circuits: 10/2 and 6-30R vs. L6-30R. Is it smarter to use a locking receptacle "just because"?

2-pole 30A circuit with 10/3. Can I make it a branch and do anything I want with it --same as the 10/2 6-30r circuit?

Thanks.

On the 30A with 10/3, you could separate them and put 2 5-30s on it.
With the 10/2 you could change it to a 5-30 by moving the white wire to the neutral bar.

You can't put 20A receptacles on them without changing the breakers if that's what you had in mind.

I gotta give credit,, you can complicate some ****.

 

[alfredeneuman]

Do you have a less complicated way to explain it?
Then by all means go right ahead.

What would you need a duplex 6-20r for?

I didn't think TR was required on 240v,but maybe i am wrong

In 2017 NEC, TR is required on nonlocking type 250V receptacles.

2017 Code Language:
406.12 Tamper-Resistant Receptacles
All 15- and 20-ampere, 125- and 250-volt nonlocking-type receptacles in the areas specified in 406.12(1) through (7) shall be listed tamper-resistant receptacles.
(1) Dwelling units in all areas specified in 210.52 and 550.13
(2) Guest rooms and guest suites of hotels and motels
(3) Child care facilities
(4) Preschools and elementary education facilities
(5) Business offices, corridors, waiting rooms and the like in clinics, medical and dental offices and outpatient facilities
(6) Subset of assembly occupancies described in 518.2 to include places of waiting transportation, gymnasiums, skating rinks, and auditoriums
(7) Dormitories
Exception to (1), (2), (3), (4), (5), (6), and (7): Receptacles in the following locations shall not be required to be tamper resistant:
(1) Receptacles located more than 1.7 m (5 ½ ft) above the floor
(2) Receptacles that are part of a luminaire or appliance
(3) A single receptacle or a duplex receptacle for two appliances located within the dedicated space for each appliance that, in normal use, is not easily moved from one place to another and that is cord-and-plug-connected in accordance with 400.10(A)(6), (A)(7), or (A)(8)
(4) Nongrounding receptacles used for replacements as permitted in 406.4(D)(2)(a)

And where are you putting them?

I bet you're excluded if you really read your post.

No, I would never put a 20a receptacle on 30a circuit.

For the 10/3 30A circuit, I want access to both 220V @ 30A and 120V @ 30A which is why I was looking at 14-30. I have some 125V 30A devices (either tt-30 or pin/sleeve) and I'd also like the option to plug in a welder, air compressor, etc. The reason why I asked about making the 10/3 and 14-30 a branch circuit is so that I could put one receptacle at either end of the garage and a third on the exterior of the garage.

What would you need a duplex 6-20r for?

I want two duplex 6-20's so I can plug in a drill press and bandsaw next to each other in one spot and then ts/ras for the other duplex receptacle.

What am I missing?

Exception:
Receptacles located more than 5½ ft above the floor.
Receptacles that are part of a luminaire or appliance.
A receptacle located within dedicated space for an appliance that in normal use isn’t easily moved from one place to another.
Nongrounding receptacles used for replacements as permitted in 406.4(D)(2)(a).

Receptacles are located at 4ft above the floor
Receptacles are not part of luminaire or appliance

Can you consider a garage to be a dedicated space for an appliance that in normal use isn't easily moved from one place to another? The drill press is heavy as F and doesn't move (and always stays plugged in) but the bandsaw is on wheels so I can pull it out when I use it and the ts/ras are also on wheels so I can pull them out when I use them.
I believe 406.4(D)(2)(a) doesn't apply either.

Do you have a less complicated way to explain it?

I want to run a 3-wire, grounded 30A branch circuit. I'd like three receptacles on the circuit. Each with 14-30 and the capacity to supply 120v @ 30A or 240v @ 30A. That's it. I want one 14-30 on either end of the garage and one outside (because rv tt-30).


For the 6-20 receptacles, I have a lot of my stuff wired for 220v (or 208 at home). I want a few duplex 6-20r receptacles along the wall in the garage so I can plug in stuff like drill press, bandsaw, ts and ras. The drill press is fixed/stationary however the bandsaw, ts and ras are all on casters so I can pull them out when I use them. Outlet boxes are 48" above the floor.


I believe because the appliances "easily move during normal use" and receptacles will not be more than 5-1/2 feet above floor, they need to be TR... but I can't find TR duplex 6-20 receptacles anywhere.

Which is why I was thinking: f-it, I'll just use L6-20R receptacles so I can comply with the nec.


Clearly I'm not understanding something. That said, I thank everyone for the replies, responses, attempts to help, etc. I appreciate it. Thank you all.

I was responding to sberry's comment "I gotta give credit,, you can complicate some ****", not your post. I understood your post and it's intent perfectly
If it was in response to your post then I apologize to sberry.

I don't think your garage falls into any of the areas denoted in 406.12 sections 1-7. Hint: not a dwelling unit.

I have a RAS and used it about twice in the 10 years I had it. Big Ole Dewalt monster. I added 20A ocpd to it (which cost as much as I paid for it) but did it simply so I could use it on welder circuit. In hindsight would do it slightly different seeing where it got parked but kept the ts 120v just to be simple. Only other thing I use besides welders 240v is pressure washer and it's fixed location.
I got lots of panel spaces, simply run another wire if I need something and try not to convolute circuits.
When I stared wiring had to use every fitting they invented, every scheme. Today I try to make a lot of it as simple as I can, not against an extra wire or circuit, not always successful but try to keep it to a minimum. I find I am better if I wire as I go vs pre planning where I park a lot of wire trying to future proof.
Filled 20 spaces in my storage building, could have used 6.
