----I my opinion, and from my personal experience, the real problems in the electrical industry starts at the state and local government levels with the lack of uniform regulation, licensing and enforcement, and ends at the manufactures and supplier level.---
Very true. Some trades have that cooperation. HVAC.
Try to buy some gas.
I tried to buy a pad for my pool heat pump, I was asked for my license. Produced my Elec ticket and the clerk responded.." Well guess you can't hurt yourself with just a pad".. Any thing more and I would have needed my refrigerant lic.
So yes, I agree with limited supply in states requireing trade licenses.
