    The different types of 400 amp load centers.

    With a higher current rating, 400 amp load centers are only used as service entrance equipment. Used to distribute power and protect circuit breakers across commercial or large-scale residential applications, 400 amp load centers are available as either a main breaker load center or a main lug load center. This special type of load center comes in both single phase, 3 wire configurations and 3 phase, 3-4 wire configurations.

    A particular load center for particular applications.

    While they come in different current ratings, the most common variety of 400 amp load centers are Siemens EQ load centers and Square D Homeline load centers. Due to their high current rating and tough construction, it is also not uncommon to find 400 amp load centers as a meter load center combination. These load centers are usually installed outdoors and built for underground service applications, which also means that they are extremely rugged and can withstand heavy weather conditions among other factors. So whether you choose a NEMA 3R load center or any other outdoor NEMA rated load center enclosure, your 400 amp load center is built to last.
