[PSUBS-MAILIST] Motor Protection

[Alec Smyth via Personal_Submersibles]

Hi Alan,

I think the key wording is "which open all conductors." My interpretation
is that either conductor could be the positive one, depending on whether
you are going forward or reversing. Or you could have an issue protecting
only one conductor if (admittedly an unlikely scenario) more than one
thruster were to short to the hull or sea at the same time.

Best,
Alec
