Sorry, but I did look, read and attempt to interpret and became confused :shock: As far as I can tell the point of bonding the radiator circuit is to make each room safe from cross contamination from the other. When plastic pipes are used, they provide automatic isolation and thereby do...

Apologies in advance for bringing this one up again, but my head is starting to hurt trying to understand certain needs for earth bonding and I obviously want to make sure everything is safe. In preparation for the electrician coming, I have bonded the hot and cold water pipes and the oil...

Wish I knew that before I'd replaced several of the others ! My switches are actually a pretty standard design ie cheap, there were a couple that didn't really match and then the two I mentioned in my original post, that REALLY don't match. Thanks for all your replies, I'll get my ass down...

:oops: Actually, I think I was the one told off ! I only raised it within this thread because I was hoping for an answer from the people who had already commented on the subject and were more likely to read this thread than a new one, at least thats what the Vulcan would say :D The...

I'm about to have my CU replaced to allow PME for my property. Would having a 100mA RCD as the main incomer then cover this new requirement or is it going to have to be individual 30mA RCD's ? I'm just asking because I suddenly feel the money I'm about to pay out for the new CU could be a...

Hi All, Prior to doing some redecorating, I've decided to standardise the light switches about my home. There are 2 plates that still need replacing. 1 > Is a single intermediate switch, it has 4 wires going into it, it is marked 10AX. I believe the 10AX indicates it is rated for up to...

Hi again, only me :D Ok, I've found an electrician that knows his stuff on PME's etc. He's provided a quote for replacing the consumer unit and setting up everything ready for the PME connection, which I'm happy enough with. Bonding the oil supply, which I'm going to discuss with him...

Yes. I had pushed the lever into the manual position this morning and left it there.

Thanks for replying Oilman. I take it, that the actuator is the silver box with the wiring coming out of it that sits on top of the valve assembly ? Just to add some new observations. Having got home from work, the heating had been on and was in the process of going cold. I've now...

I apologise in advance if this has been covered before, but I've spent half an hour searching posts and havn't found anything yet. I woke this morning to a relatively cold house, though still with hot water to taps. It appears that my Worcester Heatslave oil combi boiler has decided to break...

If you fit a filter plate to your master socket, you will not need to modify any extension plates. Neither will you need any dangling filters on them. It is the easiest/tidiest way of filtering the home. There are two contributing factors for not doing it this way. One is obviously the...

From the price you've given for a whole system filter, I think I'll leave that one as an absolute last resort, or even consider moving house first ! :wink: Wonderfull pictures of systems, unfortunately, I have limited space to play with, somehow I think my wife may get a bit upset if I take...

Thanks everyone for the new info. I was reading the WIKI section on this site and found a bit under RCD's that states : "Spurious tripping may be avoided by installing a filter upstream of the RCD at the origin of the installation." My only knowledge of filters is that of the surge...

Hi, thanks for the feedback. Ive contacted my supplier and they've contacted some form of contractor who'll be in touch with me in the next couple of days and let me know if its going to be a straight forward connection job (£21) or more "complex" ( didn't specify an amount ). I'll still...

Hi all, I'm hoping someone can help me with a bit of a problem. Ive had 2 professional electricians tell me two different things, so at this point I'm fairly confused. The problem is that every time there is a lightning strike in my area, my RCD trips. I'm sure it used to only trip when the...
