Amperage is always measured with the guage in series with the hot wire. That is the one wire is cut and the guage goes in line as opposed to some devices which have a hot and neutral (or ground).
The ampacity or amp rating of all wire is rated by the size of the wire. NM (non-metallic sheathing) wire is no different. In household wiring 14 gauge wire must go on a 15 amp breaker/ 12 gauge goes on a 20 A and 10 gauge goes on a 30 Amp.
The amp size of a wire is determined by its gauge, not the number of wires. An 8-gauge wire is typically rated for around 40-60 amps, depending on the type and insulation of the wire.
No, it is not safe to use 10 gauge wire with a 30 amp breaker as the wire is not rated for that high of a current. It is important to use the correct wire gauge that matches the breaker amperage to prevent overheating and potential fire hazards. For a 30 amp breaker, you should use at least 10 gauge wire.
10
No, you should not use 10 gauge wire with a 30 amp dryer. A 30 amp dryer requires a minimum of 10 gauge wire, but it is recommended to use 8 gauge wire to ensure safety and to meet electrical code requirements. Using 10 gauge wire may cause overheating and pose a fire hazard.
The recommended gauge of wire for a 50 amp circuit is typically 6 AWG (American Wire Gauge) for copper wire.
The recommended gauge of wire for a 30 amp circuit is typically 10 AWG (American Wire Gauge).
