My background is hvac service and I currently work on a campus doing mechanical maintenance in the denver metro area. Im interested in basic and specific electrical courses if these are available online or locally. I know of local hvac supply houses that offer 1-3 day trainings which are very useful but was wondering if these courses are available specific to lighting, wire sizing, etc at any local electrical supply houses. I would be interested in schools but with full time work and young children at home and a working wife, the workshops are easier for my current situation. I appreciate any leads, thank you very much.
