Basic Engineering Common Core (BECC) 1 Practice Test

The maximum number of extension cords that should be connected together is generally limited to two cords. This guideline is based on safety considerations, particularly the risk of overheating and potential electrical fires. When multiple cords are linked, the overall resistance increases, which can lead to excessive current flowing through the cords.

Using two extension cords allows for greater flexibility and reach without significantly increasing the risk of voltage drop or overheating. While some contexts might allow for more connections, best practices and safety regulations advise against connecting more than two to maintain electrical safety standards and ensure reliable performance. It’s essential always to follow manufacturer recommendations and local regulations to minimize risks associated with electrical hazards.
