Re: We need a lot more electricians
#42Something to keep in mind is that most homes, if they haven't been constructed within the last 10 years, likely have some non-compliance with the current electrical code. For instance, I needed to install an exterior disconnect which wound up costing me more than a thousand dollars on top of the existing electrical work I needed done. The electrician also needed to replace my existing ground wires because they are su…
Required to sheath ground in green? What on earth for? That makes ground less effective since you want any incidental contact with ground to ground the object touching it.

In most countries, I don't think you're required to update your home every time the electrical code gets a change. However, many electricians will try to sell you on this unnecessary work.
So if you are having a new socket added in your kitchen, then all the other sockets in the kitchen on the same circuit will need updating, and the breaker for the kitchen.
But you probably won't have to have your living room rewired.

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 believe the answer is that induction is more efficient at getting heat into your food. With electric, it heats up a coil that heats up your pan (and the air around it) that heats your food. With induction, it skips the coil and simply heats the pan. The pans are specially designed to contain a heating coil in them which implicitly is closer to your food. It also means the work surface tends to cool quickly (or neve…
Just to note, you don’t need special pans to use an inductive stove. Any magnetic cookware will do, which includes cast iron and most stainless steel. As an intuitive rule of thumb, if a magnet will stick to the bottom, then it’s compatible.

#45The article is touching on the important issue of homes but is missing three very important related issues. 1) The network that delivers power to the home. It's not able to handle everyone electrifying everything. If you electrify everything (electric stove, electric car, air conditioner/heater) you are going to be hard pressed in many locales to be covered by at home solar. 2) Electricity generation. We need a lot m…

I'd never heard of a 400 A service until just this discussion (it's common to have 100 A - 200 A), but it's important to keep in mind the voltage differences and that effect on total power: UK: 100 A x 230 V = 23,00 W US: 200 A x 120 V = 24,00 W Edit: I am wrong in my understanding of US power distribution. It's 200 A per leg, which the US has two of. But it seems like the UK may or may not have 380 3 Phase, so the n…
> but it's important to keep in mind the voltage differences and that effect on total power: > UK: 100 A x 230 V = 23,00 W > US: 200 A x 120 V = 24,00 W That's incorrect. The service drop in the US is 220V. It gets stepped down at the main load center to 120V for most of the regular circuits. So it's more like 48000W service in US houses.

#48We 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 tr…
Look for a "smart heat pump" water heater and you can probably get away without actually upgrading service unless you want to - 100 amp service can support a stove and water heater especially if the water heater is "smart" enough to not run when the stove is running.
You can also find a friendly electrician to "check off" on your wiring after you do most of the grunt work, this works well for areas that require permits even for homeowner-done work.

There is mooooore than enough spare grid capacity to deliver the electricity to electrify homes. We size the grid for peak capacity, not for average capacity, which means that there's a very low overall usage amount. And the big drivers of additional electricity, heating and transportation, are easily shiftable to non-peak times. And as we have smarter devices, and more time of use billing, load shifting will be easy…
Yes its designed for peak load but the load profile is changing significantly. And no you absolutely cant just load shift away heating and transportation of residential homes. That isn't cost free and we don't even have the projects in place to manage that yet.

#50Unrelated, but sharing just in case: I don't have electricity training, but last month I replaced my electric panel (upgrading to 30 circuits, keeping 100 amps) and it was easy: turn off every breaker (hiding face behind metal panel as is good safety strategy), turn off main, disconnect the meter, touch all dangling hot wires to ground (just in case, unsure if there's weird residual charge from something). Except for…
Did you upgrade your wiring? Your old breakers were the size they were for a reason.
Putting in a new panel can get you more space, or just update to a currently maintained standard for breakers so you can find and put new ones in.
