May Your Buses Be Thick and Heavy

We use 2/0 wire and heavy bus bars for battery and inverter connections.

Before, the wire grounding the battery to the trailer chassis was 12 gauge and separated from its ring terminator.

A  four post negative bus bar, 200 amp circuit breaker, battery cutoff switch, and 4 post positive bus bar with plastic cover are arranged left-to-right on and secured to a piece of plywood. Heavy 2/0 wires run between them. Red positive wires run to and from the breaker, cuttoff switch, and positive bus bar. Black negative wires run to the negative bus bar.

The plywood board with breaker, cutoff, and bus bars is mounted vertically in the electrical compartment of the Casita next to a 160aH Renogy battery. A black 2/0 wire runs from the negative battery terminal to the negative bus bar. A red 2/0 wire runs from the positive battery terminal (out of frame) to the circuit breaker. Spare wires lie in the compartment waiting to be attached to the inverter+charger+transfer switch (not in photo).
