Thanks for the sub!

Hi All new buildings are designed (electrically) before the buildings are built and therefore the electrical supply has been installed, assumptions based on experience have to be made or you take the maximum values of Ze as supplied from the DNO (you would be required to tell them what size supply you would like for the new build).

Hi, on this triangle i.e. 90, 45, 45 angles, the the ratio of the two (equal) short side with the hypotenuse is always sqrt of 2 (or approx 1.41) Please share with like minded or maybe even like and subscribe.

Hi as shown on the video X=tan(22.5)x100=41.421. Hope that helps please share with like minded people or even like and subscribe.

@@sparkyhelp3997 I wasn't using my calculator correctly. Thanks for the help!

Trust me just keep going, you will get it, and when you do it will just click and then the sky will be the limit. Keep going I presume it is only early days. Good luck.

Many thanks, Please share with like minded people. Earthing and Bonding should be checked as well as maximum demand. Only the circuit you have installed needs testing or any other circuit you have altered. Unless the client wishes the entire installation tested. Hope this helps, Please like and subscribe.

@@sparkyhelp3997 Thanks

You're absolutely right! Series circuits have that single pathway for current, while parallel circuits allow for individual control of each load. Great observation! Please share with like minded people or even like and subscribe.

Good question, to do this measure from the end to the back of bend, measure back from this point the dimension of the tray (this is your first bend). Now multiply the dimension of the trunking by square root of 2 (1.41) this will be the next bend. Maybe I will do a video on this to explain.

​@@sparkyhelp3997 Your videos are amazing mate. Especially explaining the maths. But I have a question. Who taught you all this? I've never seen it done like this before on site.

@@timh5529 Hi had a very good apprenticeship in fact the person who taught me a lot was a guy called Tim (learnt a lot), the rest is picking up from other colleagues over the years, you never stop learning.

Yes as long as the trunking dimensions are square, if not alter for your trunking dimensions. Please share with like minded or maybe even like and subscribe.

I have watch to the end. Hope that helps.

Ladder wrack will have (on the whole much larger cables therefore the bending radii will be larger and the cables will be heavier etc) It would not be advisable to try to do this. Just cut it a, remove flanges so two pieces can be joined and drilled and bolted. You need strength to support the cables. Please Share with like minded or maybe even like and subscribe.
