So your freezer shuts down when your toaster is on? A hard cap that's low enough to make a difference seems like a bad idea, there are many devices which shouldn't be cut off suddenly. And that's ignoring things like medical devices.
Of course there's already a hard cap (usually ~9kW over here), but I suspect most people never reach it.
There are plans in Belgium to charged based on peak power (something silly like "max power used in any 15 minute period"), which would drive up the cost for the average consumer without reducing demand (as people tend not to have much choice in when they use their most power hungry appliances).
- bombcar 4y agoUS houses can draw 166 KW (or half that if older 100amp service) but you’d probably be raided for running a grow op.
- elric 4y agoI think you've got your units mixed up. 100A @ 120V = 12kW. Assuming the newer homes are 200A, that would be 24kW. 166kW seems ... unreasonable, especially over 120V, that's like 1400A. Toasty.
- bombcar 4y agoAh I found 200 amps at 220 threephase which is still a bit more than most houses.
- quickthrowman 4y agoYour math was still off, 200 amps at 220v three-phase is ~76.2 kW. 200*220*sqrt(3)=76210 watts
- ars 4y agoUS homes are measured at 240 volts. 100 amp would be on each of the 120v legs. High power US home is 200 amp times 240 volts. More typical homes are 100 amp or 150 amp.
- kennend3 4y agoAs the other person posted, you are mistaken. Houses in north America are fed with two 120V "legs" and so the 100A is actually at 240V.
- rightbyte 4y ago> So your freezer shuts down when your toaster is on? That is actually not a bad idea. Would only decrease power though, not energy consumption. (Assuming the freezer is built to read the power meter and decide when to not run the compressor).
