| Hello:
Thanks for help.
There was nothing apparent on the furnace circuit board when visually
inspected; just that it became non-funtional after lightning strike.
Further testing on not possible, as was returned to HVAC company
for replacement
Nothing else in house affected, surprisingly.
BTW: what's ELCB, MCB, MCCB/RCCB ?
Guess mccb is molded case circuit breakers, but what about the rest ?
Regards,
Bob
