Ring or Radial

[Nugot747]

Hi,

Been out of the industry for 20 years and have found an interesting spark on YouTube who is very entertaining, he made a comment on one of his videos, Rings Vs Radials, would be interesting to see your views this in todays world.

Those concerns are scaremongering and contain unfounded fears.
We design circuits to function as designed, not faulty. If a circuit is installed correctly it won't become faulty. If someone incompetent alters it to make it faulty then that is also something we cannot and should not design for. Any circuit can become faulty if altered incorrectly.

Agree Andy, no one can foresee idiots interfering with things they don't or can't understand.

Run a parallel cable and alternate outlets

The best kind of radial

See a lot of 20A ring finals in the schools we test, no idea as to the reasoning behind it.

I see them in shops we've been testing also. Mostly wired in 4mm

Maybe due to the installation method and de-rating of the cable that they reduce to 20amp rather than increase the size of the conductor?
