Thanks for bringing your wisdom over here to our forum, you explained that much better than any of us.
Now about that 20 amp bathroom circuit. Here is my teenager, curling iron in the bottom of the duplex, hair dryer in the top of the duplex. What do you think happens?
If you wire this circuit 15 amps, you only have 2.5 amps left for the curling iron! If you wire this circuit 20 amps you have 7.5 amps left for the curling iron.
This was real life, just so happens I used 12 wire for my entire house, with exception of the lights. It originally had a 15 amp breaker, which could withstand the current for a short period of time but not long enough to finish her pretty little head. I replaced the 15 with a 20 and wella....long enough to get her head finished! ![icon_biggrin.gif](upload://iKNGSw3qcRIEmXySa8gItY6Gczg.gif)
It is common practice for the house to be wired to one GFCI receptacle and all of the bathrooms are protected off that one receptacle. As you know, what happens when you have two people using two 1500 watt hair dryers at the same time, like getting ready for school, or work?
How about if we start requiring 25 amp bathroom circuits!
