Current rating for al plate derating holes
WebFeb 10, 2024 · It consists of one table, whereby the designer selects the size of cable conductor and whether it is a single-core, two-core or multi-core cable. Up to six cables can be bunched together without derating. More than six cables grouped together require a de-rating factor of 0.85. Annex B is popular because it is simple to use. WebMay 27, 2024 · One final, important point! These derating percentages are cumulative. For example, if the output power at 85Vac input is derated to 90% and the allowed power is 50% at 70 o C ambient, then the maximum output power will be power derated by 0.9 x 0.5. A 150W rated power supply will be rated at a maximum of 67.5W.
