[In the UK] I need to replace the condensate pump in my basement (for pumping condensate from the boiler), and the current one is simply wired up to a standard 13A plug, but reading the instructions on the new pump (a direct replacement, same make+model), it specifically says not to do this:


"The unit should be connected to a fully earthed electrical supply. All wiring must conform to BS7671, 1992 requirements for electrical installations. The SANICONDENS® Eco/Basic requires a 220/240V single phase AC 50 Hz supply (UK specification). Do not connect SANICONDENS® Eco/Basic to a conventional plug and socket. It must be wired into a fused, unswitched, fixed wiring connector fitted with a 5 amp fuse. SANICONDENS® Eco/Basic has an Earth wire.

The wires in the mains lead are coloured in accordance with the following code:

Brown – Live Blue – Neutral Green/Yellow – Earth"

  • Brown – Live
  • Blue – Neutral
  • Green/Yellow – Earth"

[Cue stupid question] Why can't I use a normal wall plug but with a 5A fuse? What benefit is there for the connection to be unswitched for what is a fairly simple pump? Obviously I want things to be in reg's, so just trying to work out if I need to call out an electrician, just don't want to be embarrassed if he wires up a plug :)

Thanks all for any help
