We are thinking of switching some gas appliances to electric in our old farmhouse but we probably need to rework our electrical panel completely to add high amperage services for an induction range (my wife won't accept an ordinary electric range) and an electric water heater.

Fortunately our son is in training as a handyman and that means we can get him working on projects of all kinds around the farm. Of all the trades, electricity is the one that I know enough about to supervise somebody. (e.g. I am baffled by plumbing)

If you need to upgrade your service entrance, if it's within your means, go to 400A to future proof (EVs, HVAC and hot water heat pumps, induction stove, and other large loads all add up, along with colocated generation of some sort). Depending on your authority having jurisdiction (AHJ) and utility, they may require a licensed electrician to replace the raceway or similar entrance to the meter. 200A is satisfactory if greater amperage isn't available (US centric advice). Think of this as the residential version of "dig once" [1].

EDIT: Yes, you may not need 400A immediately, but if you're doing an upgrade, the cost delta between the conductors for 200A vs 400A is not substantial except for very long runs. Also, some utilities will cover the cost of a service upgrade to the meter; from the meter onward into the home is your cost. Balance cost with future needs, future labor costs, etc. Very similar to dropping a whole bunch of cheap fiber in a trench just in case you need it in the future.

I usually recommend people combine this work with a solar PV install, to capture the 30% federal tax credit towards the work (if you can justify the upgrade as necessary, which you can if your current service is less than 200A), as it has no limit on the amount you can capture as part of the install (versus the previous tax credit for electrical upgrade costs for installing an EV charging station).

This is double-great advice. It's completely obvious once mentioned but not something that may have occurred of the top of ones head. Thank-you for posting.

There are a lot of laws and regulations about electrical installations.

In many regions, doing it legally requires lots of courses and certificates. When you have invested all the time and money into getting said certificates, which is sometimes multiple years full time, you typically want to become a full time electrician to pay back the time+money investment.

That means that 'I just do electrics on the side' is becoming a thing of the past - at least in places with strict certification requirements.

There's a startup that is adding a battery to induction appliances, in part so that you can run off of a standard outlet: https://www.channingcopper.com

It's only in pre-orders, however. Edit: Looks like first round of pre-orders were limited to Bay Area and now there's a wait list for next round.

Your comment implies that you could hook up a ordinary electric range but not an induction range.

I thought induction used slightly less energy. Or is it that it uses more energy for a shorter time so the net is less but the peak is higher?

I assume I could replace my electric stove with a stove with induction "burners".

I always forget the size difference between US and UK homes (I assume toomuchtodo is speaking from a US perspective). Here, in my three-bedroom UK house I'm on a 60A service fuse and considering updating to 100A in the future (amusingly, as part of a solar PV / electric vehicle charger install).

I've never heard of a UK house having a larger than 100A service (although I imagine they exist here and there - it's certainly not common).
