Question Do most states require a licensed Electricans to do low voltage wireing: A.C. , Furnance controls, Engery control system ect??I;m not talking smaller sytems or replacement items. I;m taking about Schools, businesses ect . Say 24 volts and under??? Just curious???
Depending on what type of "Low Voltage" wiring you are talking about. If it's Class 2 wiring for instance like for a furnace thermostat, my answer is yes, it requires a licensed electrician to install the wiring. If it's communication wiring then they are exempt from licensure in the State of Michigan per Public Act 217- 338.887 Sec. 7(o). In both cases, the wiring is required to be inspected (hence a permit) per Michigan Electrical Code 80.19.
There is sometimes a snag in issuing a permit to an unlicensed person and this is being addressed at a State level for the '05 Michigan Electrical Code.
Galway, if its the state issued EC license then your assumption is correct. If its an ER license, registered electrical contractor which is county or city issued then no, they cannot do alarm work in Florida.
