Are "battery isolaters" scca approved?

[Speed Sport Engineering]

Anyone have any experience with using a battery isolator like those made by cartek and their approval by SCCA?

I just installed a MSEL unit. It’s FIA approved. My interpretation is that SCCA will accept it.

We use a simple toggle switch, a number 10 or 12 wire from the positive side of the battery to the toggle switch and from the other side of the toggle to "the car". We have used a simple high amp mil spec toggle or a mil spec toggle circuit breaker from Aircraft Spruce.

A battery like we use can deliver 400 amps instantaneously at a breaker switch and you use a 2 amp toggle?
What am i missing? Is it for a high voltage relay as used on homebuilt aircraft?

The circuit breakers David mentions above are meant to be used as on/off switches, as compared to household type breakers that aren't.

Why did you choose the MSEL unit over the Cartek?

Thanks,

Don't think they're required.

Mike,
Cartek XR is almost the same capabilities but MSEL has these differences as far as I could tell in my research:
1)switches positive
2)has CAN bus monitoring
3)disconnect command via CAN signal is possible
4)built-in short protection
