Thanks both. I have read more about this now and it seems that most people agree with you that there is no need for them in this situation.

Could you expand on that please RF?

Hi RF Lighting, I was given advice by an electrician a few months ago that all downlights should be hooded. I have a bungalow, so the top part of the downlight protrudes into the loft. I have a 2 inch space around the downlights i.e. free of installation. Also, by googling I have found...

I am looking to replace some downlights with these http://www.screwfix.com/p/halolite-satin-nickel-12v/20520#product_additional_details_container These seem to already have a fire rated hood built in, so would I be correct in thinking that they would not need any other external hood? Also...

The electricians have been this morning and done the following :- The solar circuit on a 20a MCB has been taken out of the bank of MCBs protected by a 30ma RCD. So the RCD will then protect 5 "house" circuits - 2 lights, 2 sockets and 1 cooker. The 20ma MCB to which the solar is connected has...

Hi Peter . It is not armoured cable.

The solar company have contacted me today and this is the proposed solution. In the CU, the solar circuit on a 20a MCB will be taken out of the bank of MCBs protected by a 30ma RCD. So the RCD will then protect 5 "house" circuits - 2 lights, 2 sockets and 1 cooker. The 20ma MCB to which...

Correction to above. The RCD Type should be AC according to document below published by Power One :- RCD PROTECTION INTEGRATED INTO POWER ONE AURORA PHOTOVOLTAIC AND WIND INVERTERS Power One Aurora PV and Wind Inverters (*) integrate an RCD protection device accordingly with the VDE V...

Well I seem to have opened a can of worms here... I have just quickly done a couple of google searches for 300ma RCD's and it seems the price can vary from around £72 to over £400 depending upon the type. I don't know what type is required (I think Power One recommend a type B) . I have...

That's interesting Jono. The Solar company have been speaking to Power-One who manufacture the inverter and (as far as I know) this has not been mentioned. The first solution suggested to me by the solar company is that the solar circuit is taken out of the mcb bank in the CU and instead put...

Hi Jono - what problems do you see with the above?

Thanks for all for the replies. I am trying to get the electricians back but not succeeded so far! To remove all loads from live and neutral - does this mean unplugging all appliances? Is switching off the cooker at the isolating switch ok? (The cooker is about 2 years old). Is there...

I have had a new Hager CU fitted - done at the same time as a Solar installation. All MCBs, RCDs are Hager. This is a split load CU - 7 MCB's on one side covered by a 30 ma RCD (no problems on this side) and 6 MCB's on the other side covered by a 30 ma RCD (RCD has tripped twice on this side)...

The fuse is on the output side. I will try what you suggest tomorrow. Should I not get a reading on a multimeter from the output terminals though if the tranny is OK?

I have tested the new fuse since I tried it in the tranny and that has not blown. The fuse is a small glass fuse. I have tried to read the markings on the end of it and I think it says 5A/250V but very tricky to see even under good light and with magnifying glass. The fuse holder is the black...

Thanks for reply Bernard. Photos below. So with the "~" it looks like 24V AC output. Is this a standard convention?

I found that the fuse in the transformer was blown (no continuity across fuse). A spare fuse was taped inside the cover of the transformer - I tested this and it was OK. So tried the transformer plugged into mains with the new fuse. Normally, there is a slight "hum" and you can feel the...
