Oh dear.

Fair enough, let sleeping dogs lie.

Outspoken. I am looking at drawing 2 and it says 5m to Ccu and the info I gave previously is all I have to go on and it doesn't add up.

OK lets take this one step at a time:

Leg 1 is 6m from the joint to the last fitting, but this section is 8m long, therefore the leg from the MCB to the joint is 2m long, making 8 m

Leg 2 is 3m from the joint to the last fitting, but this section has a total length of 6m, thus 3m + 3m from the MCB (1m further than leg 1)

Does this make sense to you know...

The length of the cable to the first joint is 2m, then from joint 1 to joint 2 = 1m, from Joint 1 to Joint 3 = 2m, Joint 1 to joint 4 = 3.5m, Joint 1 to joint 5 = 4.5m. You then need to add the initial 2m to each, plus the length of the each leg...

The information is on the drawing and self explanatory.

Ok but on your picture it clearly states 5m to ccu. Where I would imagine the MCBs are and also they look switch symbols not joint symbols. So I couldn't the reference point of your lengths.

Apologies, I failed to delete the JB comment in the bottom corner. The clue should have been that is stated JB still not MCB, but that is my fault, i now see why you got confused by that MB...my humble apologies!!

 

[Monkeyblaine]

Ah ok. Thank you. That makes sense now. Haha. Thanks for taking the time to see what I was talking about.

Just one more thing haha. I's the final calc correct? Shouldn't it be (2+6+3+5+3+5) rather than (11.5+6+3+5+3) as stated in your diagram?

Highly likely, I've been typing this and being attacked by my 3 year old who thinks he is a Monster robot for the last few hours...attacking me with pillows, blankets, stuffed toys and generally being mad!

It should be the total length of all the cable, so 11.5m for the longest single section, then the length of each section from the joint...will look at the diagram in a mo when...I have fought him off again!

 

[Outspoken]

Just double checked, I did do the total correct...

 

[Monkeyblaine]

Haha know the feeling have a crazy 4yr old princess myself. As I sent last message I realised I was wrong as well but. From CU to joint 5 I see the length as 6.5m. (2m from cu to 1st joint then 4.5m from joint 1 to 5). Then add the branch of legs. Where is the 11.5 from?

 

[Monkeyblaine]

Once again I apologise haha just worked it out. 11.5 from cu to last light on last leg. Then all other lengths. Got it!!!
