hello
hear term all the time now on e pay,
so what the heck does "powered up" realy mean

when I worked microwave radio relay
if some thing powered up
it meant turned it on and it worked

now I don't quite understand what anybody
means by powered up

turned it on and nothing happend ?
turned it on and smoke came out ?
turned it on and it went ohoooa ohoooa
till 20 amp breaker opened ?
turned it on and it worked ?

yours truly Mac
