INCORRECT: (presence of a faulty radiator, with the DVD and audio installation
connected on two different plugs).

Once the theory above is understood, the recommendations, which are to follow,
may seem somewhat evident. For those who have not followed to this point, simply
pay careful attention to the following elementary rules.

o

Power your entire installation from one single wall socket, and avoid connecting
any equipment that is not linked to the installation to this power source (i.e.
spotlights etc).

In this example both the humidifier and the spotlight should not be connected to the
same plug. From your single power socket, try as much as possible to use “single
point” connection rather than multi point (see below).
