How is a new single phase electric watt meter installed?

A single phase watt meter is installed in series with the meter stack. It should be installed by an electrician. A permit has to be taken out for this type of installation and the electrician is the only one that can draw a permit on the job. The wires come from the weather head down the meter stack conduit and terminate into the top lugs of the meter base. From the bottom of the meter base the wires, in conduit, continue to the distribution panel where they are terminated into the main breaker's lugs. Once the installation is completed, a declaration is sent by the electrician to the electrical inspector. Once the inspector confirms that the installation is safe, he sends a declaration to the utility company stating the service is safe for connection. The utility company connects and you have power to your distribution panel.
