Thankyou Taylor, will look into it now. Think I saw the parts in TCLs website :)

Thanks john. Testing circuits with 2 rcds will be a nightmare for me, should have thought it though a little better. Will look at other option listed in this thread and as a last resort replace the RCBOs for MCBs in the new board. Will however install the other circuits 1st as originally...

Spark-............ This is an option, and I have looked into it. If honest was a little nervy at doing this as although fully qualified... 236 pt1 and 2 the AM2 etc, most of my work for the last 20 years has been maintenance repairs, commercial and industrial. Motors, pumps, catering, and loads...

Wow, will get back to you johnD as need to confirm type of board and current circuit protection inside it. Was going to pop in tomorrow to make sure all was clean and tidy ready for Monday. Forgot my manners lol. Thanks :)

Thank you for everyone's help, think I got myself a tad confused reading your posts while eating etc. but having read all the posts again I seem to be able to follow them better now. 2 rcds (or RCBOs) at the same rating is not the best. My understanding, pressing the test button on an RCD or...

Tried everything I could think of to find breakers for the old memshield DB. Think it was memshield 2. If I could have found at breaker to fit then it was always to be my preferred choice as it would have eliminated the Rcd in series problem. Could not find memsheild 63a, or find compatible...

found the answer to the last part..... he earth is secondary in case the neutral is lost. Had a quick read up on RCBOs. Should really have done this some time back. I kind of feared that answer haha...... the old 2 RCD problem. Thanks anyway......

Endecotp, haha, exactly that one just a different size..... even ordered from the same company :).... with a white earth cable. John, Really sorry have read your post several times but cannot quite understand what it is your saying :( Feel a little embarrassed if honest, my day to day job is...

Think as they are white and pretty thin they may just not show in pics but they are there. Yes, just to clarify, pressing the test button on the contactum RCBO tripped the hager RCD.

The main incoming feed to the Hager DB it is a whooping 25mm so it maxes out the terminals in the DB, the possibility of moving this 25mm armoured cable is practically nil too looking at how its been installed. Obviously the switch fuse idea would protect the new cable against overcurrent, but...

EFL - The Hager DB I took the supply from is split load with RCD protection on both sides. PRENTICE - The SWA is protected by the 63A MCB from a spare way in the Hager DB, which unfortunately is still protected by its RCD

I have a problem.... of my own making in overcoming RCD discrimination My OH rents a building used as a nursery and she recently had a sizable wooden outbuilding installed as a kind of outside play classroom. The owners told her they were okay for me to install electrics although not 17th...

Have been asked at work to order 2 5foot twin light fittings for a non ventilated room that will be used to store various paints. I understand that normal light fittings are not allowed owing to the risk of explosion. Can anyone tell me what classification lighting I will need for this zone...

I live next to a pub garden and the pub has got loads busier and roadier this year with yobs from town. Heavy leather football come into garden frequently and many like to have a nose around when climbing up to ask for ball back. for this reason in need advise on a climber to replace old ivy...

does anyone know the name of it please? Sounds good to me. Thanks

Need some good advise, I have a garden which I have not maintained since buying the property 3 years ago due to total refurb of house. (common excuse but true) Garden measures some 50m x 20m. Was looking reasonable until beginning of summer, I used weedol on much of the garden and the nettles...

cannot remember where i saw it but there are some grids that are kind of egg box design that you can lay in gravel. These have the advantage also of keeping gravel level to. Other alternative I can think of is to lay a row of slabs under where the car wheels will drive.

why would the new cable installed be placed on the non rcd side of existing board. Is it due to tripping out the ring mains in house in event of fault? is this why it has been suggested to place on rcd side of CU in Stable. Also there is no steel work within the stable so no extre..(however...

will do, many thanks
