The MidNite Solar The original Baby box has been a huge success in filling an industry need. We now have in stock an enclosure called the Big Baby. This box is one inch larger in all dimensions. It also includes a ground box lug and mounting provisions for our short insulated bus bar. Big Baby Box is a simple housing that accommodates 1 to 4 MNEPV or MNEAC 1/2" DIN Rail Breakers. Front knock out is ready for 1-4 breakers. Knockouts are located on top and bottom for easy wiring.
