Can anyone recommend a suitable panel-mount 2-pole circuit breaker for the
240V primary circuit of a high-voltage transformer power supply? There are so
many different types of circuit breakers available : Magnetic -Hydraulic,
Thermal - Magnetic, medium-delay etc. the choice can be confusing. I would
assume an instantaneous acting Magnetic-Hydraulic would be the best but even
those seem to have different time-delay settings in catalogs I have looked
at. Grainger seems to have a good selection but the catalog listings are
confusing. I would guess a 20-25 amp rating would be good for a last line of
defense and compatible with the ratings of my house wiring. Thanks for any
suggestions. 73 Todd Roberts WD4NGG .
