I would write an RFI to clarify is you can just use THHN/THWN which is listed in Table 310.104(A) asI dont this exists in XHHW, correct? RHH-RHW I beleive it does.
I will and also look into 310.14 but I assume XHHW is not flame retardant and THHN/THWN is?? If so that's odd. I'd think if THHN is then XHHW surely would be.I would write an RFI to clarify is you can just use THHN/THWN which is listed in Table 310.104(A) as
Flame-retardant moisture- and heat-resistant Thermoplastic instead of thermoset XHHW.
I can't locate 310.104 in NECI would write an RFI to clarify is you can just use THHN/THWN which is listed in Table 310.104(A) as

I see table 310.4. xhhw-2 is flame retardant and moisture resistant so I think xhhw-2 will comply with spec I listed.I would write an RFI to clarify is you can just use THHN/THWN which is listed in Table 310.104(A) as

Not sure if 2020 or 2023 but it moved to 310.4I can't locate 310.104 in NEC
Yes it will. How does it compare to THHN/THWN in cost and availability?I see table 310.4. xhhw-2 is flame retardant and moisture resistant so I think xhhw-2 will comply with spec I listed.
Almost same..XHHW slightly higher. I believe XHHW insulation more durable than thhn????Yes it will. How does it compare to THHN/THWN in cost and availability?
Here tooMost readily available XHHW around here is aluminum conductors in sizes 6 AWG and larger
It is. When pulling it can take a lot more abuse than THHN without damaging it.Almost same..XHHW slightly higher. I believe XHHW insulation more durable than thhn????
