BS7671 page 105 reg 524.1 and table 52.3 gives the minimum cross-sectional area for aluminium cables as 16mm2.

Practice makes perfect. When doing your dog legs it's very easy to end up with the final end being offline so watch this when you replace the conduit into the bender. You will need to over-bend each bend because it will spring back slightly. When finished it's better to have an underbend than...

BS7671 page 104 reg 523.7 table 52.2 states the derating factor of cable in insulation: for a length of 50mm is 0.88, for a length of 400mm is 0.51.

Thanks for the quick reply.

Hi everyone, I have a simple question: Is there any regulation/guideline for a minimum distance between a socket outlet and a radiator, and what would this distance be. Thanks in advance for any replies.

Just been on the 2382 course and it was said that for an isolating transformer the primary and secondary windings are isolated from each other physically, so there should be no short between the primary and secondary windings.

Very nice page. Unfortunately, you may want to look at the Force and Resistance parts, because the explanation of the quantities used does not correlate with the equations and also the Tranformer Ratios part needs looking at. Hope this helps.

A happy and prosperous new year to all forum members for 2009. <EMBED pluginspage=http://www.macromedia.com/go/getflashplayer src=""http://www.thesmilies.com/countdown/newyear/main.swf?fullpath=http://www.thesmilies.com/countdown/newyear/&dom=www.thesmilies.com width=365 height=211...

You could have the them together in a lockable cupboard/enclosure away from the rooms.

Don't forget you could have a seperate RCBO for your fridge/freezer, so that your food doesn't spoil if the ring main trips out.

Yes, I was thinking more of the door entry buzzer system, lol. I didn't think of the electro magnetic type.

Thanks for the answer Tazmanracer. There is a small unit between them and the drainer is going to be nearest the hob so it should be ok, thanks.

No problem dean mac . I did think about putting it on the output of the transformer to begin with, but then changed my mind. The main reason was because the transformer would be using electricity while nothing was happening. I was thinking of a door entry system where you push the button to...

A simple way to wire it would be: mains supply (+ve) ----> under counter momentary switch ----> transformer supply (+ve) --------------> magnetic coil (+ve) mains supply (-ve) ------------------------------------------------------> transformer supply (-ve) ---------------&gt...

I have been given a kitchen rewire and was wandering if a cooker can be placed next to a sink unit? or does there need to be any separation between them? Thanks in advance.

I think I'll hold my breath though!

I use yellow crimps alot where I work and we use yellow inline crimps on 30A breakers, using 6mm

Glad to here you've passed. My course dosen't start until 23rd January, so I have a bit of time to prepare.

Congrats on passing, hope the weather is good for you tomorrow. I'm going paintballing, so I hope it's good for me too. Wont be able to see or reply to any posts for a while because I am supposed to lose my internet connection today :_| and will not get another until mid-late November, but...
