What is the proper way to flag the white conductor as a hot phase both at the panel and in the disconnect for 240v?
Is it the same as a 120v being a simple black flag on the white wire or should this be a red flag?
Further Detail if Needed:
I have a yet to be purchased A/C Condenser that will be a max of 5 ton.
During rough-in I ran 8/2 wire with ground (less than 20') to a 60amp disconnect. While I understand the breaker that will be installed at the source panel will be determined by the condenser unit I get, likely a 30 but no more than a 40amp breaker, I wanted to properly mark both hot conductors.
The 8/2 wire has a black and a white conductor. Being that there is no neutral for an A/C Condenser, I decided not to run 8/3 wire (which was not available).
