With a service having 14 single-pole circuits and 4 three-pole circuits, how many poles are minimally required?

To determine the minimum number of poles required for the given service, you need to calculate the total number of poles used by both the single-pole and three-pole circuits.

Single-pole circuits each require one pole. Since there are 14 single-pole circuits, they will require a total of 14 poles.

Three-pole circuits require three poles each. With 4 three-pole circuits, the total number of poles used by these circuits is 4 circuits multiplied by 3 poles per circuit, which equals 12 poles.

Now, by adding the number of poles required for the single-pole circuits to the number of poles required for the three-pole circuits:

14 poles (from single-pole circuits) + 12 poles (from three-pole circuits) = 26 poles.

However, if this was meant to reflect the minimum requirement by combining the counts directly, there might have been an intent to summarize simply. If you are looking for the total pole count, the proper addition yields the total needed for operation rather than the combinations per type.

So, your total calculations showcase that you would need at least 26 poles to accommodate all circuits adequately. It’s important to review the total number accurately and understand the functional aspect
