The instruction/user manual for the Aleko Sliding Gate Opener AR1550/AR2450 is at best confusing. I am an electrician with over 40 years experience, The electrical conduit opening in the base of the housing will not accept a NEC fitting. The hole has to be reamed out with a round file or a dremel tool to use a 1/2 inch NEC watertight fitting. A DIY person will struggle installing this unit.
