Good Topic!
I was at a meeting recently where a Leviton Rep gave a presentation on structured wiring for the Home. They offer a one day training course/seminar that sounds pretty good. It is a full day and costs $250 for the first person and $100 for each additional person from the same company. You get a free toolkit and can get certification as a "Certified Leviton Installer" which I think extends the warranty on work that you do with approved materials and methods.
Course Description:
The Certification Seminar is a full day workshop. The course covers all aspects of planning, installing and testing a category compliant system. It also covers industry standards and provides suggestions on marketing your business to audiences such as builders and home owners.
They will be having 2 of these seminars near me (Long Island) in mid November and I will be trying to attend one. So I'll let you know how it is.
If you'd like to see some more info on this and links to scheduled seminar locations and dates it is on their website at:
