Upgrading Circuit Panel in Home

I have one large feed panel and 2 subpanels. It's ideal to work on as you can shut off the feed panel to each one separately if you need to work on it. I was able to upgrade the subpanels myself this way.

Hiring a licensed electrician is probably your best move, unless you want to learn how to run load calcs.

I don’t think anyone will be able to help you with the information you provided, other than recommending an electrician.

If you just need more space for additional circuits, and a electrician gave you the advise, adding a sub panel is likely the way to go.

I've replaced a couple of panels in houses. It's not that hard if you have any inkling of DIY work. Get a generator for your fridge and lights to do the work.

Biggest thing you need to figure out is if your house has 2 wires w/ground or not. If you don't have a ground then upgrading the panel is kind of pointless.

If you're simply doing a remove and replace on the panel, it shouldn't take you that long. Don't go cheap on the panel and breakers. I went with SquareD plug on neutral bar. Biggest thing you want to do is make sure all your connections are tight as any loose ones will result in sparks/excess heat.

You need a certified electrician. Period!
