The AllSpark Insulated Surface Mount Copper Busbars have been developed by use here at Offroad Living to be used with the AllSpark Surface Mount manual reset Circuit Breakers(see Flush Mount Busbars here).
There’s a combination of 4 sizes (2, 3, 4 or 5 tabs), plus the option to purchase a full length 18 tab busbar for bulk jobs that can be cut to size.
Surface mount circuit breakers may be installed on each individual tab using the 3-5 tab surface mount options.

Q: It says 150A continuous rating, my inverter uses a larger circuit breaker than this, can I use this busbar?
A:Yes, the 150A continuous rating is an overall net value (taking into account inputs and outputs)not including the first position where the battery input feeds in. By placing the inverter circuit breaker in the first position, along with the battery input feed (left or right), the current essentially flows directly through the circuit breaker, and not along the busbar itself.
The setup below is an example of a surface mount circuit breaker installation, where you can see the inverter breaker with the input feed from the battery on the left. You then place the remaining circuit breakers in descending order along the busbar.
Q: The circuit breaker for my inverter has an M8 lug, not M6, can I drill this out?
A:Yes, this is safe and standard practice.
