Choosing electric conductors for dc installations

electric conductors

Electric conductors are essential elements in any electrical installation. Their selection for DC installations differs from the procedure used in AC. On the other hand, for the process of acquiring this material, it is important to know that cable is not the same as a conductor. For this, we recommend the post Cables and electrical […]

Voltage drop in DC electrical conductors due to electrical resistance

voltage drop in DC

After ampacity, or the maximum current-carrying capacity of a conductor in amperes, voltage drop is the most critical parameter when selecting wiring. Therefore, here we present how to calculate voltage drop in DC electrical conductors. This phenomenon involves the power loss that occurs in the conductor due to its electrical resistance. As a result, the […]
