Boiler control fed from plugtop

[DPG]

Only thing I can think of is that it is in the manufacturers instructions.

Maybe so. Strange if they do actually specify this though. Daz

Some of the Gas Boiler manufacturers instructions say to use a plugtop...

Just proves you can't win either way eh Daz

Note: Mains supply to the boiler must be
through a fused double pole isolator
situated adjacent to the appliance. The
isolator must have a contact separation
of 3 mm minimum in all poles.

A few years ago I had a really big fall out with the plumber on site about this topic.

New builds, 8 houses and all with combi boilers. I fitted DP switched fused spurs. Mr plumber says that is wrong and I have to fit a socket! The conversation went a little like this:-

Erm.. why do I have to install a socket?

Because it says so in the installation book.

Why does it ask for a socket?

So we can turn it off.

"Use the bloody switch and turn it off" (or words of that effect)

They say a plug, it has to be a plug.

:banghead: Phone the help line and tell them that the electrician has fitted a double pole switched fuse spur and is that adequate?


It took 30+ mins on the phone to speak to someone that knew what they are on about to "yes a DP switched fused spur is more than acceptable".

Bloody plumbers

A 13A plug is both fused and double pole.

How many power cuts does he have normally?

If Grid power cuts are a common problem you could install a duel supply Isolation switches set up at the CU. Wont look very pretty in a domestic home but it is suitable for his needs/concerns. Locking off is essential and an instructions list will have to be placed near the Iso set up but it is do-able and can feed the house (obviously only for restricted circuits... lights, small socket circuit and his boiler).

Only done this once in a remote country side house but it works great. All depends on the home owners ability to understand the importance of locking off Generation supply whilst under Grid supply etc etc etc. Also change the generator plug to a 16A commando

That sounds like an accident waiting to happen unless the isolators are interlocked, it would be better using a double pole changeover switch

A 13A plug is both fused and double pole.

And should easily meet the minimum 3mm contact separation

I agree!!!

In fact my very own Worcester 37cdi is run off a plugtop with a 3A Fuse. (as a "temporary" measure in 2008!!)


Someone in this thread brought up the question of Manufacturers Instructions so I was just showing what the Worcester instructions have to say.
