electrical box has high leg A high leg system with a neutral is not "corner grounded" A winding is CENTER TAPPED (XO) for a neutral point and connected to ground. A corner ground is used on a strait 3 phase, 3 wire Delta system, that has no neutral.
When it comes to bonding fabrics to metal, using the right type of glue is crucial for achieving a strong and durable bond. Fabric-to-metal projects often require a specialized adhesive that can effectively adhere to both porous fabric .

Water that seeps into cracks and breaks in the service cable can run down the cable to your electrical panel box. Moisture that enters the panel can corrode electrical wiring and circuit breakers and even rust the bottom and inside of the panel box.
The high leg, or wild leg, or snake leg, or bastard leg, is found when a service supplies a building with 240 V 3 phase. Because at least some of the lights and equipment will need 120 V, one of the transformers is sized .High-leg delta (also known as wild-leg, stinger leg, bastard leg, high-leg, orange-leg, red-leg, dog-leg delta) is a type of electrical service connection for three-phase electric power installations. It is used when both single and three-phase power is desired to be supplied from a three phase transformer (or transformer bank). The three-phase power is connected in the delta configurat.
The high-leg conductor is also called the “wild leg,” “stinger leg,” or “bastard leg.” Other important NEC rules relating to the high leg are as follows: Panelboards — Since 1975, panelboards supplied by a 4-wire, delta .
Sounds like you might have a bad neutral. Contact the utility, and have them check it. This is a dangerous situation, that need immediate .High leg wiring, also known as “wild leg” or “stinger leg” wiring, is a type of electrical distribution system used in some older industrial buildings. It is a three-phase system where one of the legs, also known as the “high leg,” has a . A high leg system with a neutral is not "corner grounded" A winding is CENTER TAPPED (XO) for a neutral point and connected to ground. A corner ground is used on a strait 3 phase, 3 wire Delta system, that has no neutral.
What is a high leg delta connection? 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 .
If a 4-wire, delta-connected, three-phase (high-leg) system supplies a panelboard, the high-leg (or wild-leg) conductor which operates at 208V to ground must be terminated to .
The high leg conductor must be marked as orange, that is consistent everywhere, but not which phase it is unless it is related to bus bars. "Conventional wisdom" however . For high Leg delta supply, the electric power supply company installs three transformers to provide 120V, 208V and 240V (1 & 3 Phase) supply voltage levels based on the end user requirement. The primary side of these three step-down transformers are connected to the 4.5k-7.2kV supply.
The high leg, or wild leg, or snake leg, or bastard leg, is found when a service supplies a building with 240 V 3 phase. Because at least some of the lights and equipment will need 120 V, one of the transformers is sized larger and center tapped.High-leg delta (also known as wild-leg, stinger leg, bastard leg, high-leg, orange-leg, red-leg, dog-leg delta) is a type of electrical service connection for three-phase electric power installations.

High leg wiring, also known as “wild leg” or “stinger leg” wiring, is a type of electrical distribution system used in some older industrial buildings. It is a three-phase system where one of the legs, also known as the “high leg,” has a voltage that is significantly higher than the other two legs.
