Service Call, How to install a new 200 AMP Service #electrician #bluecollar
What happens here
The new service cable, now prepared, is routed through a new metal conduit, often referred to as the service mast or riser, which extends vertically up the side of the house from the meter base. This conduit is securely fastened to the exterior wall using appropriate conduit straps, spaced according to local electrical codes. The top end of the conduit is fitted with a weatherhead (also known as a service head or service entrance cap). This component protects the internal wiring from weather elements like rain and snow and provides a neat entry point for the utility service drop wires while directing them downwards to prevent water entry. The cable is pulled through the conduit from the meter box upward to exit through the weatherhead.
Goal: Securely install the new service riser conduit and route the service cable through it.
