36A is a lot. Wouldn't that melt the insulation on the wires?


No. The current carrying capacity of a cable is determined by (mostly)
how hot it gets.

A ring final circuit is designed to run forever at 32A with a max of 20A
in any part of the cabling.

And maybe as much as 27A (for 2.5mm^2 T&E) depending on how its installed.

So unless you are right up one end of the ring, 36A would quite possibly
never take either leg of the ring to max cable conductor temperature.
