3mx3m Non fire rated portable structure(similar to school portables) has been built for a small office. A 25kVA 600-120/208V transformer has been installed on a plywood backboard with a 600V primary disconnect and the secondary 225A, 120/208V panel. This is installed in Ontario Canada.
My first question is
1.Can this type of transformer be installed in this building which will be used as an office
2. Can the transformer be installed on plywood backboard (Does it violate UL approval?). Quick and urgent response is appreciated.
