This lecture argues that this fear might be misguided. Social collapse is also a prevalent theme in in contemporary culture and popular entertainment. For some scholars, the collapse of human civilisation and even human extinction are real possibilities. We are already seeing the disastrous consequences of the climate crisis around the planet, and as global carbon emissions keep rising the future is uncertain. The generator continues to run for about five minutes before it is shut off to cool down.Ole Martin Sandberg is the first lecturer of the RIKK and GRÓ-GEST Lecture Series for Spring 2020 with a lecture entitled “Climate Crisis and “the Logic of Masculinist Protection.”” The lecture will be held Thursday 23 January, 12:00-13:00, at the Lecture Hall of the National Museum. When the power outage ends, the homeowner can move the transfer switch back to the “Utility Position and restore utility power to the circuits. It avoids starting multiple electric motors at the same time which could overload the generator and cause the generator main breaker to trip. This allows the generator to take the load gradually instead of all at once. One at a time, each circuit breaker is turned on about five or ten seconds apart. The homeowner moves the transfer switch from the “Utility” position to the “Generator” position. To avoid overloads, all the circuit breakers in the transfer switch are turned off. The generator main breaker is turned on.Īt this point, the generator is ready to supply power. When a power outage hits, the homeowner starts the generator, then connects the generator cord from the generator outlet to the inlet box. The circuit breaker in the main panel that connects to the transfer switch feeds power to the transfer switch, which then distributes that power to the essential circuits through the circuit breakers located within the transfer switch. ![]() ![]() Portable Generator Safety Rules Manual Transfer Switch Operationĭuring normal operation, electricity flows from the utility into the main service panel and is distributed through circuit breakers. Essential appliances usually include refrigerator and freezer, sump and well pumps, one or two lighting circuits, and the furnace. Using a breaker rated for more current could allow the wires to overload and start a fire.Ĭhoose circuits that power essentials. Use the same size breaker in the transfer switch as the main panel for each circuit. Connect wires from a 15-Amp breaker in the main panel to a 15-Amp breaker in the transfer switch. The installer removes the wire from the circuit breaker in the main panel and connects it to the circuit breaker inside the transfer switch.Ĭircuit breakers protect wires from overloading whether the power is supplied from the generator or from the electric utility. The circuits that receive power from the generator connect to circuit breakers in the manual transfer switch. Using the Standardized Wiring Practices of the NEC Ensure Safe Electrical Installations Some transfer switches allow positioning both main breakers in the “OFF” position.Ĥ Part Series: Planning a Manual Transfer Switch Installation Essential Branch Circuits The two main breakers in the transfer switch are connected by a mechanical device that only allows one main breaker to be in the “ON” position at any time. These wires connect to a branch circuit breaker in the service panel. The other main breaker connects to wires from your service panel and supply the switch with power from the electric utility. One of the main breakers connects to the wires that come from the inlet box and control the power from the generator. The manual transfer switch has two main circuit breakers similar to the main breakers in your service panel. How to Use a Portable Generator for Backup Power Transfer Switch Main Breakers Generator placement is important for safety. The manual transfer switch connects permanently to the plug inside the inlet box. The generator is placed where exhaust fumes from the generator will not enter the home through air vents or windows. ![]() The inlet box is mounted to the home in a convenient location. The generator power cord has four wires for ground, neutral and two wires that each carry 120 volts, for a total of 240 volts. The plug end connects to the generator receptacle and the receptacle end plugs into the inlet box. Most people keep them in their garages or sheds.Ī generator cord carries electrical current from the generator to an inlet box. Portable generators move anywhere and are not permanently connected. A transfer switch, now required by the National Electric Code, connects to the circuits in your electrical panel that you’ll need most during a power outage, like a furnace, lights, well pump, television, garage door opener, etc.
