Question:

Question:
Will this work to install a 15A 120AC breaker for installing shore power access from my house to my van?
Answer: Yes! This is a perfect application for this enclosure. -
Question:
How do you wire this with no bus bars included?
Answer: Only the hot wires go into the box. So, assuming you have 2 breakers, you have 2 wires coming in and being attached to the breakers with 2 wires leaving the other side of the breakers going to the load. The negative wires can go straight to the battery or to the load. For me, I have 1 breaker between the positive wire from the solar panel to the solar controller ( 44 volts at about 10 amps so a smaller wire and 20 amp breaker is used). The controller changes the 44 volts to 13.5 volts and sends that back to this box and a 50 amp breaker on the way to the batteries. The higher amp breaker and 4 or 6 gauge wire is needed from the controller to the battery because when you decrease the voltage, you increase the amps. The negative wire from the solar panel runs straight to the converter and then to the battery. The gauge of the negative wire changes to match the positive wires. If you are wiring this between the battery and two separate loads, you just run the negative wire from the battery to the corresponding load.
Blue Sea Systems Magnetic Circuit Breakers Editorial Review
The Blue Sea Systems SM Panel A Series CB is a reliable circuit breaker enclosure that is perfect for installation of shore power access from your house to your RV or van. Designed to accommodate 15A 120AC breakers, this box is a must-have for RV enthusiasts who want to keep their electrical systems in check. The box only accommodates hot wires, so you need to have two wires coming in and attaching to the breakers with two wires leaving the other side for the load. The negative wires can go straight to the battery or to the load. The box can also be wired between the battery and two separate loads, by running the negative wire from the battery to the corresponding load. Though the bus bars are not included, this product works well with BlueSea breakers. This is a high-quality product that is designed and built for specific purposes, which is why it comes with a higher price tag than comparable generic ones that fit normal breakers. You might need to drill holes for plastic strain relief clamps and purchase a ground bar to complete the installation. It is worth noting that this product is not large enough for wire > 10 AWG, and if you have a 50A breaker fed with 6 AWG, you will need to cut non-standard openings. Additionally, to use it, you must drill holes for the strain relief. Overall, this product has received positive reviews for its excellent quality, reliability, and purpose-built design. However, some customers have criticized it for being overpriced, lacking flexibility, and not offering great protection for a main circuit breaker (high voltage).
