For most applications the generator itself is just the starting point. You will most likely also need a transfer switch, a starting battery, a pad to set the generator on which can be concrete or a formed area or landscaping rock, an electrician to change over the wiring, add the transfer switch, add the service disconnect if needed, a plumber to extend the gas line to the generator, a gas regulator if needed, miscellaneous plumbing supplies to connect the gas line to the generator itself, a technician to install the generator, start up the unit, and program it for its exercise cycle.
