Voltage Limit 277 Vac L-N!
To avoid eGauge meter damage do not exceed 277 Vac between Lx and N ports. Do not attempt to substitute the Neutral connection with a ground. Neutral connection is required when using the AC mains voltage connector.
Step 1: Install a two-pole (split-phase) or three-pole breaker (three-phase) in the distribution panel so that it will provide voltage access to all phases. Refer to the example wiring diagram relevant to your installation type for details.
Step 2: Open the breaker and properly de-energize the system to ensure there is no power on the breaker contacts.
Step 3: Connect voltage from the new breaker and Neutral to the included 5-pin Power Plug using THHN #12 stranded copper wire, or by using an appropriate Power Whip accessory as described below:
Service or panel voltage | eGauge voltage port |
| Phase A up to 277 Vac L-N | L1 AC mains connector |
| Phase B up to 277 Vac L-N | L2 AC mains connector |
| Phase C up to 277 Vac L-N | L3 AC mains connector |
| Neutral (required, do not omit, do not sub ground) | N |
| DC 9-60 Vdc (optional) | 2-pin DC voltage input |
Information
For installations utilizing the EV1000 high voltage sensor or for installations where there is no Neutral available refer to the correct installation example diagram for details regarding voltage connections.
