Electric garage doors have been manufactured with ease-of-use in mind. This idea has been carried over into the area of installation. Automatic garage door opener units come supplied with a normal 3-pin plug as standard, so will plug into a standard household socket. Yes, there’s none of those funky Euro-only or American plugs to worry about. The 3-pin plug socket should be situated in relative proximity to the garage door opening (if you have a very long garage); however, if you do not have power available in your garage, we recommend that you contact a certified electrician.
