Can I temporarily wire something in a Class 1 Div 1 area using TC-ER-HL if I need to zip tie it or would it have to be Armor Clad if I do it at all? I would rather have a permanent fix but I am just wondering because it is outdoors and I have no cable tray if I am even allowed to do this? Also, I looked at Type P and it doesn't clearly state if it can be outdoors can someone help clarify that for me.

There are two answers:
1.) It may be temporary, but the wiring method must still be compliant with Section 501.10(A). See Section 590.2(A).
2.) The work is done under a "Hot Work" permit. This is essentially temporarily reclassifying the location. See Section 590.2(B).
NOTE: These are based on the 2023 NEC.
