I have a new 2.5 ton central a/c it cools fine the problem is when it first starts my lights dim for just a second. I'tsnot blowing the breaker so I am not overloading the circuit?

I think the start currant on all idems is 125 times the running currant, just for a micro second.

not to worry. all you're experiencing is just a little "bump" in your power. i've seen it happen more than once,even in a brand new building that i wired for a customer.

Any large motor-operated appliance, like a central air conditioning compressor, will draw multiples of its steady electrical draw when it first starts.  Thus, a 3 ton unit nominally rated for 16 amperes of current at 220 volts may easily draw 48 amperes on startup - causing a fall in voltage throughout the house which lasts a half-second or so.  If the unit is properly fused or breakered at the panel board, there is no harm done.

WHAT SIZE BRANCH CIRCUIT ARE YOU RUNNING?
WHAT IS THE NAME PLATE CURENT OF EACH PART?
CAN YOU HEAR ARKING AT THE METER OR PANEL?
CAN YOU PAY AN ELECTRICIAN TO FIX THIS?
HOW OLD IS THE DWELLING WHICH HAS THE PROBLEM?

THIS IS NOT A FIX FOR A HANDY-MAN
