I'm not an Electrician. Mechanical Engineer through school, designed conveyors for 3 years, then architectural fountains for the last 19 years. The electrical part of fountains is more interesting than the hydraulics, there's much more variety. I talk to Electricians from all over the country every day, and I have a great deal of respect for them and for those using this site (too mushy I know). There's a wealth of knowledge on this site.
