and further comprising one or more power distribution connectors mounted in the control box to connect the one or more power distribution lines. ### Claim 8 (depends on 7) The control system of claim 7 further comprising a circuit breaker mounted in the control box and coupled to at least one of the one or more power distribution lines; and wherein the circuit breaker comprises an operator switch located on an external surface of the control panel. ### Claim 9 (depends on 1) The control system of claim 1 further comprising a switch coupled to the control panel to disengage electrical power to at least one of the one or more generator control components when the control panel is open. ### Claim 10 (depends on 1) The control system of claim 1 wherein the control panel rotates between an open position and a closed position via the one or more linkage mechanisms. ### Claim 11 (depends on 10) The control system of claim 10 wherein each of the one or more linkage mechanisms comprises a hinge. ### Claim 12 An electrical enclosure that houses one or more generator control components of a generator, the electrical enclosure comprising: a plurality of side panels; a bottom panel coupled to the plurality of side panels; an enclosure cover coupled to the bottom panel and/or at least one of the plurality of side panels via one or more joint members that enable actuation of the enclosure cover between an open position and a closed position, so as to provide selective access to an interior of the electrical enclosure; and a microswitch coupled to the enclosure cover to electrically disengage at least one of the one or more generator control components when the enclosure cover is in the open position. ### Claim 13 (depends on 12) The electrical enclosure of claim 12 wherein the one or more joint members couple the enclosure cover to the bottom panel and/or at least one of the plurality of side panels at a lower end of the electrical enclosure; and wherein the enclosure cover covers a side and a top of the electrical enclosure when in the closed position. ### Claim 14 (depends on 12) The electrical enclosure of claim 12 wherein the enclosure cover comprises an outer surface having mounted thereto: generator controls for operating at least one of the one or more generator control components; and a feedback system to display generator operating parameters. ### Claim 15 (depends on 12) The electrical enclosure of claim 12 wherein the electrical enclosure further comprises: a back cover having one or more openings formed therein to accept a power distribution line therethrough, and one or more power distribution connectors mounted within the electrical enclosure to connect the power distribution line to the generator. ### Claim 16 (depends on 12) The electrical enclosure of claim 12 mounted in a multi-chamber generator housing having an engine, a muffler operatively coupled to the engine, and an alternator driven by the engine positioned in the multi-chamber generator housing; and wherein the alternator and the muffler are positioned in separate chambers of the multi-chamber generator housing. ### Claim 17 (depends on 12) The electrical enclosure of claim 12 wherein each of the one or more joint members comprises a hinge. ### Claim 18 A standby generator comprising: a standby generator enclosure comprising: a base; a back wall extending generally vertically from the base; and first and second sidewalls each extending generally vertically from opposite ends of the base; an engine-generator set mounted to the base; and a control system to control operation of the engine-generator set and that is mounted proximate the back wall within the standby generator enclosure, the control system comprising: a control box that houses generator control components therein; and a control box cover joined to the control box to actuate between a closed position and an open position, the control box cover covering a top portion of the control box when in the closed position and uncovering the top portion when in the open position, so as to provide selective access into the control box. ### Claim 19 (depends on 18) The standby generator of claim 18 wherein the standby generator enclosure further comprises a first door and a second door, the first door being hinged to the enclosure to rotate over a top of the first sidewall and the second door being hinged to the enclosure to rotate over a top of the second sidewall; and wherein the first door and the second door allow access to the control system from a top of the standby generator when rotated to an open position. ### Claim 20 (depends on 18) The standby generator of claim 18 wherein the control box cover comprises standby generator controls. ### Claim 21 (depends on 18) The standby generator of claim 18 wherein the control box cover covers a front of the control box opposite the back wall when in the closed position and is joined to a lower end of the control box to actuate between the closed position and open position. ### Claim 22 (depends on 18) The standby generator of claim 18 further comprising a switch mounted to one of the control box and the control box cover, the switch configured to: sense when the control box cover is in the open position; and disable one or more of the generator control components when the control box cover is in the open position. ### Claim 23 (depends on 18) The standby generator of claim 18 wherein the back wall and the control box include an opening formed therein, the opening in the back wall and the control box configured to receive a distribution line therethrough that receives power from the engine-generator set;
