Bus duct is used for the effective and efficient supply of electricity in mostly industrial locations. Copper or aluminum is used for the conductor of bus duct that be insulated and enclosed completely for protection against mechanical damage and dust accumulation. A bus duct system is an effective method of distributing power to your switchgear and various loads. However, bus duct problems can lead to catastrophic damage and extensive downtime. Allow for the space requirements and weight of the bus duct. You may need to change other components or select a different style of bus duct for your installation. If you are installing bus duct outside, select a housing type that sheds rainwater - rather than pooling it on top of the housing.
