What is service cable?
A cable supplying electricity to a building, either by an overhead wire or in an underground conduit.
What are service mains?
Service mains is tapping of electrical energy from the supplier’s pole to consumers premises. Or it is a means of providing electric power supply from the existing pole up to the meter board.
What is a secondary service connection?
Often a service-connected condition will result in a disability or disease that was not incurred in service but because the service connected condition caused it, VA will also pay a benefit. This is called secondary service connection.
What is overhead service connection?
