Page 14: Installing And Connecting The Meter
Chapter 2: Meter Installation 13 The meter is considered “permanently connected equipment” and requires a disconnect means (circuit breaker, switch, or disconnect) and overcurrent protection (fuse or circuit breaker). The meter draws up to 100 mA, therefore the rating of any switches, disconnects, fuses, and/ or circuit breakers is determined by the wire gauge, the mains voltage, and the current interrupting rating required. - Page 15 Installing and Connecting the Meter be used. The rest of the drill guides (located at the bottom, back and sides of the enclosure, each with two sizes: ¾'' and 1'') should remain sealed. Figure 10: AC wiring drill guide 3. Install the bracket on a wall or pole, with the semi-circles facing downward, as shown below.
