A 309A is a Construction and Maintenance certification A 309D is a Construction and Maintenance certification with an electronics endorsment. I do believe that is no longer available. A 442A is an Industrial certification. There are no other licenses unless you include the Ontario Master's certification.
I was talking to an ESA inspector and according to him electrical work is not regulated in the province of ontario.If it was only licensed electricians would be able to preform any electrical work.The Ontario health and safety act allows for the preformance of work by owners and competent employees not just electricians. Further more 442A electricians who were licensed before July 2001 must still renew.Apparently 442a's were the first to pay for there classroom seat in school in leu of paying license renwal fees.He thinks it's the same for all 309a and 442a electricians who go through the government program.The only difference between the two is the type of work preformed,production as opposed to construction and both can work in either field without sanction He is 100% positive Ontario is NOT regulated and probably never will be.This why a master electrician need not be a qualified electrician. cheers
I've done it and i know of many 442a electricians working in construction right now.Why does inspection allow it if it's illegal?I also see 309a in the auto plants and machine tool maintaining and building the lines.The 309a and 442a take the same school program just write a different test.I was also told the 442a replaced the 309c.One license is no better than the other.The 442a makes more money simply because they work production.In windsor ford ony hires 442a.Chrysler will only hire 309a and GM hires both this i know for a fact and there is no wage difference between the two in the plants or the construction sector.Go to Ontario Job futures and you see that some the job descriptions are the same. cheers
