What is ampere rating of 16 gauge wire at 120 volts?

For a 16-gauge wire at 120 volts, the ampere rating would typically be around 10-12 amps. However, it's important to consult the specific standards and guidelines provided by regulatory bodies like the National Electrical Code (NEC) to ensure safe and appropriate usage of the wire.

What do you use the inverter for on roblox?

The Inverter is a sort of Backwards device.Let's say if you wire up a button to an Inverter and the Inverter is wired up to a Wiring door. When the Button is turned off, the door will open. When the button is turned on, the door will close.


2001 4runner Has 120W lighter outlets you have a 300W inverter for your 300w laptop how can you wire this correctly?

You put it togather. If the lighter outlet is rated at 120 watts [that's 10 amps at 12 volts] maximum, then that means that the receptacle, wiring to it, and the fuse cannot carry a 300 watt [25 amps at 12 volts] load, AND SIMPLY PLUGGING IT IN, as suggested in answer 1 should result in blowing the fuse for that circuit. Do NOT let anyone talk you into replacing the 10A fuse with a 25A fuse, as that is a guarantee for burning up your wiring, and possibly your car. However, you do not mention whether the 300 watt rating for the inverter is the OUTPUT or INPUT RATING. IF, and ONLY IF, when you check the INPUT wattage rating [should be on a label or stamped into the outer cover of the inverter], if it indicates an INPUT rating of 120 watts [10 amps at 12 volts] or less, then you can just "plug it in." If the inverter input current rating exceeds 10 amps at 12 volts, then it will not work. To provide adequate power for your inverter, it would be necessary to add-on a new circuit from the battery, or the main fuse panel, with properly sized wire[s] for the load, a proprly sized fuse to protect the wire[s], and a socket also properly rated for the electrical load.j3h.
