(Form 1S Meter)

Purpose
:

This type of service is for older homes in which the electrical service has not yet been upgraded to a modern 3 wire 120/240V configuration. It is also useful for any 120V load in which 240V will not be required. (Such as, a business sign with 120V lighting, or an electric fencer).

Key Points for Metering:

  1. Ground (neutral) wire must go to the right.
  2. Hot (120V) wire must go to the left

Common Mistakes:

  1. Don’t connect the grounded (neutral) conductor to the left side of the meter. A parallel path through earth ground may inadvertently bypass the current coil with a portion of the current flow. The result will be a partial loss of revenue!
