Hi folks,
After searching on the web and this site, I couldn't find the answer, so I hope you guys can help..
NEC is NEC, and there is not much sense in questioning it. That said, it's always good to know the "why's", the real-life reasons behind one thing or another.
1. What is the rationale behind the dedicated 20A laundry circuit requirement? What kind of equipment in the residential laundry room, aside from the washer/dryer which get their own circuit(s) anyway, may require so much power?
2. Why are the MC support requirements (every 6 ft) are looser than those for AC (every 4.5)? In my experience, AC is a much more robust cable, so why does it (AC) have to be supported more frequently?
