Wiring a standby generator
Manual mains transfer
For portable or fixed generators
A plug-in point is fitted on an outside wall. This is the point at
which the generator plugs into. From this point a cable is installed
which runs to your utility supply (sometimes they are close by,
ideally the plug in point is next to your outside utility meter
cabinet, though not always)
Next, a transfer switch is installed. This device is for safety
reasons, where it would be impossible for the generator and the
utility supply to clash. In essence you have utility supply or
generator supply, you can have one or the other but never both at
the same time. The transfer switch is a legal requirement and for
good reason.
If a Power Cut
1) Turn off all unnecessary load in your house / business (assuming
the generator cannot supply normal loading)
2) Plug the generator into the plug-in-point (all cables supplied)
3) Start the generator
4) Wait a few seconds for the generator to stabilise
5) Turn the transfer switch to generator supply
You now have power, however; you must take note of power usage, (a
meter can be provided ) care must be taken not to overload the
generator.
