I have a rent house that started as 1 or 2 rooms and was then enlarged with additions. Probably built in the 40's or 50's back when electric was used mostly for lights.

In probing some electrical gremlins recently, I noticed the Service feed lines were pretty small, maybe 1/4" or less. There are many more loads on it now, bigger refrigerators, window A/C units, Washer, Electric Space heaters, etc. and I'm wondering if the lines are big enough.

My question is, how would inadequate service lines manifest itself? Lowered voltage on Demand? Dimming lights? What should I look for?

I'm really most concerned that appliances would be prone to early failure due to low electric supply.

Thanks in advance for your responses
