Question: 1 / 400

When selecting and sizing extension cords or power cords, what should be considered?

Only the length of cord

Connected load and potential voltage drop

When selecting and sizing extension cords or power cords, it is essential to consider the connected load and potential voltage drop. The connected load refers to the total amount of electrical power that the devices being powered will consume. This is critical because the cord must be able to safely carry this load without overheating or becoming a fire hazard.

Additionally, voltage drop is an important factor, especially over longer distances. As electricity travels through a conductor, it experiences some resistance, which can cause a drop in voltage by the time it reaches the device. If the voltage drop is significant, it may result in insufficient power being delivered, potentially leading to inadequate performance or damage to the equipment.

Evaluating these factors ensures that the chosen power cord can effectively and safely meet the requirements of the connected devices while minimizing risks associated with electrical hazards.
