Electrical packages are beneficial when customizing and modifying shipping containers for various reasons. You might need to light up storage to ensure everything is easier and safer to access. You might need electrical outlines on the unit's interior or exterior to power up tools, portable refrigerators, and other items. This modification is optimal for 10-foot, 20-foot, and 40-foot shipping containers.

When you have light and power, it's easier to customize shipping containers to meet your needs. For example, because there are limitless possibilities for shipping container conversions, you want to ensure the electrical is adequate to support those projects. For example, if you're converting a shipping container into a portable medical facility, you'll need electrical outlets and overhead lighting to ensure patients receive the best care.

Depending on how many lights and electrical outlets you need and the size of your shipping container, you'll need a breaker panel containing the appropriate number of circuit breakers. For example, if you're modifying a 10-foot shipping container with two outlets and four lights, the breaker panel needs two circuits. Or, if you want four lights and six outlets in a 40-foot unit,  the break needs at least three circuits.
