Survey the premises. The VPhase device is designed to sit above or alongside the consumer unit, therefore, access to and room for the unit needs to be assessed. The suitability of the consumer’s fuse board also needs to be checked, as some early style distribution boards will not be suitable e.g. Wylex Re-Wireable style boards.

When applicable circuits have been re-configured then essential ‘dead’ testing can be carried out.

Once the ‘dead’ testing is complete then the VPhase supply is to be energised. When switched on, the unit will carry out a self-test, which is indicated by a permanent green light and a red light, which flashes on and off for a short duration.
