Such identification shall be placed at each point on the system where a connection is made if the grounded conductor is also present. High-Leg Marking. On a 4-wire, delta-connected system where the midpoint of one phase winding is grounded, only the conductor or busbar having the higher phase voltage to ground shall be durably and permanently marked by an outer finish that is orange in color or by other effective means. (This is required in NEC article ). Phase 1 - Black, Phase 2 - Red, Phase 3 - Blue, Neutral - White, Ground - Green, Green with Yellow Stripe, or Bare Wire, If the wiring system has one phase at a higher voltage than the others, using a "high-leg" connection, that phase's wires should be marked with orange. Ground – Green, green with yellow stripe, or bare wire. When powering higher-voltage devices, be sure you are labeling wires and cables accurately and add safety Missing: high leg. Neutral – Gray wire. and search the NEC forum for High Leg Color Code. The NEC says that volt wires are yellow, orange and. Jun Re: What color is a hi-leg? High-Leg Marking On a 4-wire, delta-connected system where the midpoint of one phase winding is grounded, only the conductor or busbar having the  . A substitute for high leg delta is WYE or star-connected secondary with the centre point grounded. The phase with V supply to the ground is called High-Leg or Orange leg. This conductor needs to be marked permanently by orange outer finish where ever connection is made. On a 4-wire, delta-connected, 3-phase system, where the midpoint of one phase winding of the secondary is grounded (a high-leg system), the conductor with V to ground must be durably and permanently marked by an outer finish orange in color or other effective means []. A. On a 4-wire, delta-connected system where the midpoint of one phase winding is grounded, only the conductor or. Jan High-Leg Marking.

There was no breaker Panel, just a feeder to a large can, and everything all motors taped off this!! Someone wrote on the J box cover Blue = High leg. V single phase motors for the pool equipt. This was in a vault for an old condo complex for the pool equipment. The high leg was on the blue colored C phase. NEC Article requires that the high leg bus bar or conductor be permanently marked with a. Single-pole breakers should not be connected to the high leg. However, to accommodate utility meter configurations the high leg is permitted to be the “C” phase where metering is part of the switchboard or panel board. The NEC Code requires that the high leg be identified by an orange color (it was often referred to as a red-leg delta) or by other effective means and is usually the “B” phase. By doing so, we are creating a split phase supply as well as a three-phase delta connected supply. A high leg delta connection is a configuration in which one of the windings in a delta connected secondary of a transformer is centre-tapped and grounded. It is also known as red leg connection or wild leg connection or orange leg connection.
