"Minis" Conduit Hanger help

[OldeTimer]

I was at Home Depot an saw the "Minis" are listed with numbers and an associated EMT pipe size. A #0 is for 1/2" emt.

The question.

What size of PVC if the proper Mini?

#0 1/2" EMT
#1 3/4" EMT
#2 1" EMT....

A size "0" is for 1/2" EMT or 3/8-1/2" pipe or rigid conduit. The od of rigid conduit is the same as for PVC conduit.
However using that size of that type of support may be a violation of the following section of the NEC.

352.30 Securing and Supporting.
PVC conduit shall be instal⁠led as a complete system as provided in 300.18 and shall be fastened so that movement from thermal expansion or contraction is permitted. PVC conduit shall be securely fastened and supported in accordance with 352.30(A) and (B).

Some AHJs will approve that where the screw is left loose, of the next size larger clamp is used to permit the required movement.

What size of PVC if the proper Mini?

Typically one size up to allow for the thicker conduit wall and/or movement, as mentioned above.
