The original Baby box has been a huge success in filling an industry need. It does have it’s short comings though as it is a very small enclosure. MidNite has created an enclosure called the Big Baby to overcome the Baby Box smallness. This box is at least one inch larger in all dimensions. It also includes a ground box lug and mounting provisions for the Midnite MNSBB Short Bus Bar. Holds up to four MNEPV DIN rail mount breakers.
