![]() ![]() Other forum participants report being told that their servers have water damage and will have to be rebuilt – a process that may take several days. A common complaint is that lack of official communication about what's going on. The fourth wire is ground and connects to the generator’s metal chassis and to the ground bus in the manual transfer switch.OVH reveals it's scrubbing servers – to get smoke residue off before rebooting READ MOREĪnd in various online discussion forums, affected customers continue asking for estimates about when service will be restored. ![]() Another wire serves as a neutral or return for the 120-volt wires. Two wires each carry 120 volts for a total of 240 volts. The cables have four wires configured in similar way to an electric dryer or electric range cable. A 30-amp cord has connectors rated at 30 amps and will only connect to 30-amp receptacles. Distributor or manufacturer supplied cables have the correct connectors for the amount of current they can handle. Generator Cablesĭedicated cables connect a 240/120-volt generator outlet to the inlet box. Only use cords with a minimum rating equal to the generator outlet rating. Don’t rely on guesses or that no one will make a mistake. Keep extension cords on hand that will supply the maximum amount of current that might be drawn through the cord. If someone plugs another appliance into the cord, the cord could overheat and cause a fire. For instance, using a 16-gauge extension cord to run a 10-amp appliance off a 20-ampere generator receptacle. If a receptacle has a 20-amp circuit breaker, then it could supply 20 amps of current, and a 12-gauge extension cord is the minimum size.Ī common mistake is to size the cord by the appliance requirement. Size extension cords based on the current that the generator receptacle is capable of supplying. Only use outdoor extension cords with the correct gauge wire. Tip: After disconnecting power from the generator, turn the fuel valve to off and let it burn the remaining gasoline. Finally, the generator is turned off, allowed to cool, and put away. The generator main breaker is turned off, which removes power from the cable and receptacle panel. The manual transfer switch is returned to utility mode to restore power to the home. When the utility restores power, the process is reversed. Individual circuits in the transfer switch are ready to receive power. After it warms up, the generator’s main breaker is turned to on. With the manual transfer switch in the generator position and the generator main breaker turned OFF, the homeowner starts the generator. The dedicated power cable plugs into the generator panel and into the inlet box. When a power outage occurs, the homeowner moves the portable outside for placement in a safe location that won’t gather standing water or allow deadly exhaust to enter the home. Returning the switch to the utility reverses the action and reconnects utility power. When that happens, the circuits supplied by the generator are isolated from the utility lines and connected to the generator lines. It is a manual device that requires a human to throw the switch from utility to generator. During an outage, the portable generator supplies electricity through a dedicated generator cable that connects the generator to an inlet box which feeds power to the switch.Ī manual transfer switch is exactly what its name states. Circuit breakers in a dedicated panel controlled by the switch distribute electricity to the circuits chosen at installation. Backfeeding is Dangerous and Illegal. Never Backfeed Your House With a Generator.Ī manual transfer switch is the best way to connect your essential circuits to the generator. Never connect a generator to a home through an appliance outlet. Buy an extension cord that matches your generator outlet. Tip: A 30-Amp Cord will have a different plug than a 50-Amp Cord. ![]() It’s also possible to power a 120/240-volt Appliance like an electric dryer. Appliances without a cord and plug like furnaces, central air conditioners, electric ranges, electric water heaters, and most well pumps fall into this category.ġ20/240-Volt Extension Cords: These extension cords may have multiple outlets on one end and a single, 120/240-Volt outlet on the other. However, permanently wired appliances won’t receive power this way. This method works fine for appliances such as refrigerators and freezers, or a sump pump that is keeping the basement dry during a storm. Plug an appliance into the extension cord. Plug the cord into the generator receptacle. 120-Volt Extension Cords: Connecting appliances to a portable generator with extension cords is the most basic option. ![]()
