How do I calculate the extension cable length?

The length of the extension cable is based on the swimming pool design drawing or the customer's actual measurement. The factors that affect the length of the extension cable are mainly the following two points:

1. The accurate distance from the power room or power source to the pool.
2. Whether extension cables are needed between the pool light strips for interconnection.

For example, for the swimming pool lighting scheme shown in the picture, we can easily calculate the required extension cord length in two parts.

1. The distance from the power room to the pool is: 10 meters.
2. The extension cable between the pool light strips is: 10 meters.

Therefore, the customer needs to purchase 20 meters extension cables.

Our engineers will design the most cost-effective swimming pool lighting system for you. Generally, customers only need to order the extension cable according to the length we recommend.
