How far should wires be kept from the metal vent connector on a gas appliance?
SIX INCHES
Which one of the following is a reliable indicator of service amperage?
White wires can sometimes act as black wires in 240 volt circuits. Which one of the following is a reliable indicator of service amperage? The answer is THE SIZE OF THE SERVICE ENTRANCE CONDUCTORS. The size of the service entrance conductors is the most reliable indicator of service amperage.
What is the safest replacement for a 20 amp fuse?
the circuit wire is sized for a 20A fuse. If you replace it with a 15A fuse it will not overload the wire and will blow when the continuous current exceeds 15A so yes you can safely replace the 20A fuse with a 15A fuse.
What are the two basic functions performed by switchgear?
There are three basic functions of switchgear power systems: electrical protection, electrical isolation, and control. Switchgear power systems are the combination of electrical disconnects that serve the function of isolating electrical equipment. The electrical disconnects can either be fuses or circuit breakers.
Is 14 gauge wire OK for a 20 amp circuit?
You can not use 14 AWG anywhere on a circuit that has a 20A breaker. If you are putting 15 amp receptacles on a 20 amp circuit with 12 gauge wire, then you MUST use the screw terminals, not the back stab terminals. Just use the side terminals.
Is 12 gauge wire large enough to supply this current?
Answer Expert Verified The maximum amount of current an electrical wire can conduct is measure in terms of Ampacity. For a 12-gauge wire the Ampacity is greater than 20 A. Therefore the answer to this is “Yes”.
What is 4 gauge wire used for?
6-gauge are used for cook tops and ranges carrying 40-50 amps. 4-gauge are used for electric furnaces and large electric heaters protected at 60 amps.
What gauge of speaker wire should I use?
Speaker wires that are anywhere between 12 to 16 gauge are most commonly used for connecting speakers to an amplifier or an Audio/Video (A/V) receiver. A lower-gauge number indicates a thicker wire, while a higher-gauge number indicates a thinner wire.
Is 12 AWG speaker wire overkill?
It isn’t overkill, 12 gauge I would use for pretty much everything. The longer, 12 gauge is better than the thin stuff.
How many watts can 12 gauge wire handle?
General Purpose Cords
| 14 – Wire | 12 – Wire |
|---|---|
| Recommended 80% Wattage Load: 1440 watts (120 volts). Max Wattage Load: 1800 watts (120 volts). | Recommended 80% Wattage Load: 1920 watts (120 volts), 3840 watts (240 volts). Max Wattage Load: 2400 watts (120 volts), 4800 watts (240 volts). |

Is 14 gauge speaker wire good enough?
Thick wire (12 or 14 gauge) is recommended for long wire runs, high power applications, and low-impedance speakers (4 or 6 ohms). For relatively short runs (less than 50 feet) to 8 ohm speakers, 16 gauge wire will usually do just fine. It’s cost-effective and easy to work with.
Is Underpowering a subwoofer bad?
Underpowering a subwoofer isn’t inherently bad for the sub. Not giving it enough power just means that the music will sound weak and lack detail. The clipped signal tries to make the sub do things it’s not designed to do, which leads to it tearing itself apart or overheating and burning out.
Is 100w enough for subwoofer?
In fact, it’s probably safe to consider 12-inch, 100-watt subs as the minimum. Be wary of subs with less than 100 watts, and if the driver is smaller, you’ll need a lot more power.
