I have a 100 amp main in my breaker box. I was told that I could use 150% of this. is that true?

Well, here's how it is. If you have 100 amps to work with...lets see what you have in your house.





1) stove - 40 amps


2) dryer - 30 amps


3) washing machine - 13 amps?? close


4) air conditioner - 30 amps


5) fridge, microwave, dishwasher - all need to be on there own circuit of 15 amps each - by today's code Ontario, Canada


6) toaster, coffe maker, toaster oven - all have a high draw of power on start up about 10 - 13 amps each


7) inground pool pump - 10 - 12 amps


8) hot tub - 220 volt - 8 - 10 amps


9) baseboard heater - 20 amp circuits


10) furnace - 3 - 6 amps


11) lights , fans, tv stereo, computer...although don't draw tons of power by themselves do add up


12) bathroom jaccuzzi - 12 amps


13) everything else I didn't mention





Although it is unlikely all of these items would be on at the same time...(your house might looking like a mechanical Christmas tree) it is for sure that the 100 amp service could support the total draw. Even more assundry items like shop tools, electric lawnmower, could be added. I am not sure of the total percentage of base total amperage, but you do the math. It is clear that the big ticket items could conceivably be on at the same time. I am sure that you will not have a problem putting what you want on the service, unless you are starting a grow house and the cops find out..then it's a matter of '; I hemp you have a good lawyer, because the electrician will become very redundant.I have a 100 amp main in my breaker box.

You normally do not have everything turned on and running at the same time so you do not use 100% of the 100 Amps. The total ampere rating of all of your breakers can total up to 150 Amps. It would be a very rare occurrence that you would be using a total of 100Amps. out of any combination of the 150Amp.total.
