EMT Sleeve for PV Wire

[shortcircuit2]

All are limited to a maximum of 122 degrees F ambient temperature...in the USA.

Do you know if there is any other non-metallic conduit type, that is more suitable for installing outdoors in sunlight, in applications such as this?...

I pretty sure RTRC would work great. RTRC is just geek speak for fiberglass reinforced epoxy, or just fiberglass conduit. No expected sag, though it may just a tad over time and exposure.

Now obtaining, pricing, and installation are all a bit more challenging than PVC.

355.12(D) has the 122 degree F temp limitation...

50?C ambient temperature, same restriction as PVC [352.12(D)].

If you installed in a 60?C ambient, you wouldn't be able to use a 60?C wiring method (re: 110.14(C)(1)(a)].

Other than that, I have no idea why the NEC limits use to 50?C ambient.

UL 2515 Standard for Aboveground Reinforced Thermosetting Resin Conduit (RTRC) and Fittings says....

1.2 The products specified in this Standard are intended for use at -40?C (-40?F) to 110 ?C (230?F). The products are for use above ground in exposed and concealed locations. The products are also suitable for use below ground by direct burial or by encasement in concrete.

Compare to UL 651 Standard for Schedule 40, 80, Type EB and A Rigid PVC Conduit and Fittings...

1.2.3 The following restrictions apply to use of the Schedule 40 and Schedule 80 rigid PVC conduit and fittings mentioned in 1.1.1:

a) Use at 50?C (122?F) and lower ambient temperatures and

b) Use with 75?C (167?F) wiring, but the conduit and fittings may be used with 90?C (194?F) wiring if they comply with the construction (see Conduit for Use with 90?C Wire, 6.15) and marking (see 8.2.1, 8.2.4 and 8.2.5) requirements covering use with 90?C (194?F) wiring.

It certainly helps to not need to think about grounding.

don't know. Used EMT for 13 years.

PVC was originally developed for inground use...and it should of stayed there.
