Question 15 (Mandatory) (1 point) A number of factors have to be considered when sizing the cable of an electrical circuit. Which of the following factor is not required? The full load current of the circuit. The ambient temperature in which the cable is installed. the mupply voltage of the circuit.

When sizing an electrical cable, one of the essential factors to consider is the full load current of the circuit, as it determines how much current the cable must handle under normal operating conditions. Ambient temperature also plays a crucial role since it can affect the cable's performance and the heat it generates. However, the supply voltage is generally not necessary for cable sizing, as it's more related to the voltage drop calculations rather than the current-carrying capacity. In practical terms, think of cable sizing as choosing the right-sized shoes for your feet. If they’re too small (like an undersized cable), your toes will be cramped and could overheat. Too big? You might trip over your own feet (or experience more voltage drop). The goal is to find that perfect fit so that everything operates smoothly and safely!
