My house lights dim slightly whenever I press a flipper button on my pinball machine. I've tried running a super long extension cord to other outlets in the house to rule out the circuit that the pinball machine is on but it seems all other circuits are also affecting the over head lights in the room my pinball machine is in. I think the electricity draw is too much for my circuit breaker.

How can I fix this?

Do I need ConEd to install a higher power line to my house? What would I ask for from them or from an electrician?

Is there some battery backup or capacitor that I could purchase and place under the pinball machine to account for this electricity load?

My house will also dim when things like my audio amplifier are turned on, just like kevmad experiences. It's not just limited to the pinball machine but is much more noticeable because of the constant flipper usage.

The house was built in 1958. Not old but not new.

On my circuit breaker, the sticker on the panel door lists 150 amps. Is that too low? If I add up all of the individual circuit breakers the number is well over 150 amps so maybe I need a bigger line to the house and maybe I need a new circuit breaker?

I only used a super long extension cord to test playing the pinball machine from a different circuit thinking the circuit that my pinball machine is on is overloaded. Thank you all for your thoughts and time.

Thank you all. It seems like my next step is to contact ConEd, followed by an electrician.

Does anyone here run their pinball machine with an uninterrupted power supply (UPS) underneath? If things get expensive, this may be an affordable way to go.

Not yet, no progress.
