View Patent ↗A system for use with an electrical distribution panel having a bonded neutral connection. In some embodiments, the system includes a generator having a first bonded neutral connection and a ground fault circuit interrupter. The system also includes a neutral bus that is connected to either the bonded neutral connection of the distribution panel or the bonded neutral connection of the generator. Additionally, the system includes a switch for disconnecting the neutral bus from the bonded neutral connection of the distribution panel and connecting the neutral bus to the bonded neutral connection of the generator.
1. A system configured to be used with an electrical distribution panel having a bonded neutral conductor, the system comprising:
a generator having a first bonded neutral conductor and a ground fault circuit interrupter;
a neutral bus configured to be electrically connected to either the bonded neutral conductor of the distribution panel or to the bonded neutral conductor of the generator, the neutral bus not being electrically connected to ground; and
a switch configured to electrically disconnect the neutral bus from the bonded neutral conductor of the distribution panel and to electrically connect the neutral bus to the bonded neutral conductor of the generator.
2. The system of claim 1 , further comprising a second panel configured to house the neutral bus and the switch.
3. The system of claim 2 , wherein the second panel is configured to be positioned proximate to the electrical distribution panel.
4. The system of claim 2 , wherein the second panel includes one or more breaker switches configured to be connected to at least one load and to the neutral bus.
5. The system of claim 1 , further comprising a plug associated with the generator, the plug configured to receive at least one line conductor, the bonded neutral conductor, and a ground conductor of the generator.
6. The system of claim 5 , further comprising an intermediate connection assembly positioned proximate to the generator and configured to receive the plug and provide connections to a panel positioned remotely from the generator.
7. The system of claim 1 , further comprising a ground bus configured to be electrically connected to a ground conductor of the distribution panel and to a ground conductor associated with the generator.
8. The system of claim 1 , wherein the switch is configured to be manually actuated by a user.
9. The system of claim 1 , wherein the switch includes at least one associated fuse assembly.
10. The system of claim 9 , wherein the fuse assembly is a breaker device rated for approximately 30 to 50 amps.
11. A system configured to disconnect electrical connections of an electrical distribution panel associated with a utility power supply and to connect to electrical connections associated with a generator, the system comprising:
a switch configured to electrically disconnect at least one load from a bonded neutral conductor associated with the distribution panel and to electrically connect the at least one load with a bonded neutral conductor associated with the generator, the switch comprising;
a first neutral terminal configured to be electrically connected to a bonded neutral conductor of the distribution panel;
one or more first line terminals configured to be electrically connected to at least one line conductor of the distribution panel;
a second neutral terminal configured to be electrically connected to a bonded neutral conductor of the generator;
at least one second line terminal configured to be electrically connected to at least one line conductor of the generator; and
a ground bus configured to be electrically connected to a ground conductor of the distribution panel and to a ground conductor of the generator.
12. The system of claim 11 , further comprising a neutral bus configured to be electrically connected to the switch.
13. The system of claim 12 , wherein the neutral bus is not electrically connected to ground.
14. The system of claim 11 , wherein the switch includes at least one fuse assembly.
15. The system of claim 14 , wherein the at least one fuse assembly is a breaker device rated for approximately 30 to 50 amps.
16. The system of claim 11 , wherein the switch is housed in a second panel separated from the electrical distribution panel associated with the utility power supply.
17. The system of claim 11 , wherein the switch is configured to be manually actuated by a user.
18. The system of claim 11 , further comprising a panel configured to house the switch, and wherein the panel is configured to be positioned adjacent to the electrical distribution panel.
19. The system of claim 11 , further comprising an intermediate connection assembly positioned proximate to the generator and configured to receive the at least one line conductor and the bonded neutral conductor of the generator, and to provide intermediate line conductors and an intermediate bonded neutral conductor to the switch.
20. The system of claim 11 , wherein the switch is configured to be manually actuated by a user.
