Manual Changeover Switch
How It Works
The manual changeover switch is wired directly into your electrical distribution board (DB) on your premises. This allows you to route generator power to your entire property or just to specific, critical circuits, depending on how it is wired by your electrician.
The manual switch features two built-in indicator lights that display the presence of power from either the municipal mains or the generator. As an optional extra, a buzzer or siren can also be fitted to the switch to provide an audio cue the moment mains electricity is restored.
Various sizes are available in both single and three-phase configurations. You should always size the manual switch based on the largest load (Amperage) that will pass through the switch.
Operational Rule: 30 Second Wait
The generator requires time to get up to speed and stabilize before the manual switch can be placed on "Generator." The recommended wait time is 30 seconds. The generator should be started whilst the switch is in the "Off" (neutral) position. Only once it has run for the recommended time should you move the switch to the "Gen" position.
Battery Maintenance
When using a Manual switch, you must ensure that the generator's starter battery is kept charged. Ideally, you need to have an automatic trickle charger installed to keep the battery topped up so the generator is ready to start during an outage.
