Do you think I needs derating for 4x individual cable in one pipe conduit in three phase system ?, is I needs spacing for same amperage ?
1x35mm amperage is 208a, but 4x35mm amperage 137a, load is only about 100a maximum
And do you think I needs derating for ground cable inside pipe ?, rated is lower when in air (1x35mm2 is 169a, 4x35mm2 is 140a), rated from manufacture is only available in air and ground, no in pipe tables
