Connecting to the mains
DANGER: Danger of fatal accident due to electric shock.
▶ Disconnect the boiler from the mains power supply
before working on the boiler. Guard against
unintentional re-connection.
All Worcester boilers require a permanent live.
A mains supply of 230 V - 50 Hz is required.
External controls are suitable for volt free installation (or 230V via the
relay supplied with the 50-V2 and 65-V2 boilers).
Wiring to the boiler must be in accordance with the current I.E.E.
(BS 7671) Wiring Regulations and any local regulations.
Wiring should be a 3 core PVC insulated cable, not less than 0.75 mm²
(24 x 0.2mm), and to table 16 of BS 6500.
Connection must be made in a way that allows complete isolation of the
electrical supply such as a double pole switch having 3 mm contact
separation in both poles, or by a three pin connector, serving only the
boiler and system controls. This boiler is equipped with a double pole
switch [1]. The means of isolation must be accessible to the user after
installation.
The electrical connection to the mains supply should be readily
accessible and adjacent to the boiler.
If the supply cord is damaged, it must be replaced by a qualified
electrician to avoid a hazard and must be an original spare part.
The electrical supply for both the boiler and the system must be taken
from the same fused spur outlet.
