[TenTec] magnetic breakers ?

[Mark Erbaugh]

I bought a couple (minimum order) 20a magnetic breakers for my Pegasus.
When I acquired an Omni V, I put one on that. However, I discovered that it
never tripped before the overcurrent protection in the rig did. I have an
LDG AT-11MP and when I activate the auto tune if I forget to back down the
power, the Omni V will sometimes shut down on overcurrent. At least that's
what I assume is happening: something inside the rig shuts down, and the
frequency display digits go blank. The S-Meter back light stays light, so
the rig is still getting some power. Cycling the power switch on the Omni V
resets the radio. This happens whether the Omni V is connected to the TT
power supply or an Astron RS35A.

The question is then. is the magnetic breaker needed?
