What is the normal humidity level for outdoor electrical distribution boxes

The relative humidity range should be 45% to 75%. Excess humidity can compromise the insulation properties of electrical components, leading to potential short circuits or failures. The table below indicates the summer and winter design conditions in U. Design of Air Conditioning systems. In humid conditions the warmer air is the more water vapour it holds. Effects of condensation on electrical equipment Corrosion risk: Condensation can cause metal parts to rust, reducing the structural strength and electrical conductivity of the equipment. Install hydrophobic vents at the.
