Switchgear temperature rise
(OP)
Anyone any guidance on how to keep the temperature rise of an LV (400V) Switchgear cubicle below 60K (ambient 35 deg) for UK use. I need to know how to calculate current carrying capacity of copper and ensure that the cubicle has sufficient venting to keep temp down. Any advice would be well appreciated.
