Hi
The request below was added to a post sent the other day that was thankfully answered, and I suspect
it has been missed, so I have sent as a 'new topic'
Basically, I was installing a direct replacement combi bolier circulating pump (Grundfos 15 - 50/60 130).
BUT the connector block on the new pump was faulty and I couldn't connect the live wire, so the pump
had to be returned.
The new pump arrived yesterday morning, within 24 hours of contacting them (they collected the faulty pump).
This REPLACEMENT SECOND NEW PUMP has come supplied with a long "suppression lead".
This long lead will make it easier to wire up the pump away from boiler but this throws up another question.
THIS IS WHAT I FORGOT TO MENTION ON ORIGINAL POST
I forgot to mention that when I went to disconnect the OLD pump I saw that the LIVE and NEUTRAL wires
were connected the wrong way round (live in neutral connector).
I was going to connect as the original pump was wired up i.e. the wrong way round but then I thought if I
do this and it blows the new pump I wouldn't be able to send the pump back as faulty.
I'm sure somewhere long ago that I read that swapping the 'neutral and live' around in certain
situations this is possible - but I didn't want to take the chance.
So I'd appreciate just a few more answers;
1)
Should I follow the WRONG way round wiring i.e. live to neutral connection and neutral to live
connection OR WIRE UP as it should be i.e. neutral to neutral etc?
2)
When I connect the long suppression lead to the main cable coming from the boiler do I just use a plastic
connector block and wrap some electrical tape around it?
3)
I have got some CHOC BLOCKS for Halogen lighting would this be ok to use to connect this long
suppression lead?
4)
Does anyone know what this suppression lead does?
