@@sparkyhelp3997 you see the way you set it up and marked it for the second bend is there a way to do it just by measuring and accurately

Yes I'll cover it in due another video... keep watching.

Thank you, I have used in my example 36A as the design current, these figures are for my design to show how to do it (it is not based on 9.5kW shower - if this is what you have then base your calculations on 41A). The 40A is the protective device size, this is not the design current (current drawn by the load) of the load. So to sum up diversity is based on design current, not protective device sizes.

Thank you for watching, the current will be equal in in each line. see: ukposts.info/have/v-deo/ZWJjam5_mGhzmYk.html hope that helps. Please share with like minded or like and subscribe.

I think these are single phase supplies - therefore I=P/V (no power factor mentioned) I1&I3= 38.26A I2=18.26A then as before for 20A Neutral current. Hope that helps. Please like and share.

The Voltage across the parallel part will be the same voltage i.e. V1 will be the same voltage across R2 & R3 voltage across R1 can be found by using ohm's law V=IT x R1 Hope that helps check out the following this may help ukposts.info/have/v-deo/ioKLfo-abnmC2Jc.htmlsi=HJun4SFvo_ppMC2d Please Like and share with like minded people, or maybe even subscribe.

Why thank you - you should not have gone to so much trouble. But may be you could give me some pointers where you think it could be improved.

Glad it helped! Yes the maths can be a little bit of a challenge, but remember most metals will increase in resistance with temperature and insulators tend to do the opposite. Please share with like minded and like and subscribe.

No you use Uo as it is Zs=(Uo X 0.95{Cmin})/Ia - this is used to find the Max Zs of protective devices. Hope that helps. Please share with like minded or maybe even like and subscribe.

Many Thanks, yes If I had a £ every time an apprentice has told me no one uses the cable... Sadly when others in the class hear this they switch off, they think they can see it once and are able to repeat - they do not realise it is a skill.

@@sparkyhelp3997just so you know I have been a qualified electrician for thirty seven years. Pyro is still used just not very often as it’s a lot more expensive than TW&E,even SWA is still a bit cheaper than pyro. And yes working with pyro is a skill learnt over many years.

I have used Tallow, that was white and hard when cold (animal fat). This is translucent like Vaseline. Glad you watched Please Share with like minded maybe even Like and Subscribe.

@@sparkyhelp3997 it took me ages to figure out as im not good at maths. But it looks like both equations bring us to the same result haha

Good question! As these devices are on at night typically, and when they turn on they will likely be on for a period until warm and their own thermostat turns them off. As the OSG says it is impossible to calculate Max Demand. Have you got a smart meter this will show your max demand (it would be interesting). Without further information you could use the OSG recommendations for heating devices, but these heaters will be on when most other things are turned off. Sorry it is not really a right or wrong answer for you. In summary as a calculation you may need two max demands one for day time and one for night time.
