NOTE: There are two options to identify the wire with phase identification sleeve:
• Option 1: Colored sleeves for temperature grades C and D are available in basic colors-red,
yellow, and blue. These can be installed on the wires to identify phase.
• Option 2: PTFE heat-shrinkable sleeve in natural color can be installed on the wires with phase
identification mark, Phase A, Phase, B, or Phase C, printed on a high temperature identification
sleeve. The sleeve is installed on top of the PTFE heat-shrinkable sleeve or adjacent to the
sleeve.
