Modification of Old Electrical Work

Using a 3000 watt amp with a 300 watt speaker can potentially damage the speaker due to overpowering it. The excessive power can cause the speaker to blow out or distort the sound quality. It's important to match the power ratings of the amp and speaker to prevent damage.

For 6 can lights on a 15 amp circuit, you can use 14/2 AWG (American Wire Gauge) NM-B (Romex) cable. This cable consists of three wires: a black (hot) wire, a white (neutral) wire, and a bare copper (ground) wire. Make sure to consult local electrical codes and regulations before proceeding with the installation.

Yes you can. It will provide better protection because it will blow quicker than a 20 amp if there is a fault in the circuit.
Not advisable. If the normal current is little more than 15 amps, then the fuse will blow. If the actual current is less than 15 amps, then it would work.

The correct answer is; that depends entirely on the capacity of the circuit to which you will be connecting the fan.

If the circuit (including switches, circuit breakers, wire size) has sufficient available capacity, connecting the larger fan will not be a problem. Otherwise, it is possible that even such a small increase in power consumption can cause problems with the wiring... depending on the circuit.

There are two ways to do it. The easiest is just to put a built-in motion sensor on the one light. The switch would have to be on for the motion sensor to work. If you just want the motion sensor to work without a switch, you need to run unswitched power directly to the light.

If there is no room for a new 30 amp breaker, you may need to upgrade your electrical panel to accommodate the additional load. It is recommended to hire a licensed electrician to properly install the new circuit and outlet for the dryer to ensure safety and compliance with local codes.

Turn the power off to the circuit first at your Breaker/Fuse panel. Once you know that the circuit is dead, remove the old fixture.

One of the 2 wires goes on the black, the other on the white. If there's a bare ground, ground that to the junction box where the fixture is going. Secure the fixture in place with the provided hardware, and turn the power back on at the breaker/fuse panel. If you did something wrong the breaker will trip/fuse will blow.

The black wire originating from a breaker box or fuse box is the live wire. However, in certain cases, the grey (or white) neutral wire can also be live. For example, the black wire may feed a lighting outlet, and if the neutral wire is broken on its way back to the neutral bar in the panel, then the neutral wire from the lighting outlet will be hot, because there is an electrical path from the black wire, through the light, and to the neutral. The point is, always check with a voltmeter before assuming the white or grey wire is not live.

You talk about tubes specifically so I assume the 60 watt fixture is also designed for tubes. In such a case you should not use a higher wattage tube.

If you were to replace a 60 watt incandescent bulb with a compact florescent of 75 watts you are correct that the heat would be less. If heat were the only de-rating factor you would probably be okay. Not sure how this is handled in the code.

For a 50 Amp load, a 6-gauge aluminum wire would be suitable for most installations. It is important to consult local electrical codes and regulations to ensure compliance with safety standards.

It depends on your voltage.

Power (P) = Current (I) * Voltage (V)

800 amps at 1 volt is 800 watts or 0.8 kW.

800 amps at 120 volts is 96,000 watts or 96 kW.

800 amps at 34.5kV is 27,600,000 or 27,600 kW.

William J. Newton is credited with inventing the three-way light switch in 1916. The design allows for a light fixture to be controlled from two different locations.

A 220 VAC breaker can be single pole or double pole depending on the application. For standard 220 VAC circuits like most household appliances, a double pole breaker is typically used. However, in certain situations where only one hot wire is needed, a single pole breaker can be used for 220 VAC circuits.

There are a few different ways.

If there is a disconnect before the panel, it is usually labeled with it's max capacity or what the maximum fuses are, assuming it is a fused disconnect.

If no disconnect is present, look at the main breaker for the entire panel. You can always check the main wires coming into your panel but opening a panel is EXTREMELY DANGEROUS and should only be attempted by a trained Electrician.

To calculate the amperage, you can use the formula: Amperage (A) = Power (W) / Voltage (V). If you know the voltage the fan motor operates at (e.g., 120V), you can divide 85 watts by the voltage to find the amperage. In this case, if the voltage is 120V, then the amperage would be approximately 0.71 A.

GFCI breakers are typically available in lower amperage ratings, such as 15 or 20 amps. 100 amp GFCI breakers are not common due to the high level of current they need to interrupt. It is more common to use GFCI protection at the branch circuit level for smaller circuits.

Pull cords for bathroom light fittings are a safety feature as they help minimize the risk of electric shock when hands are wet. Additionally, pull cords are easy to reach and operate, making them more convenient for turning the light on and off in a bathroom setting.

No they are not. Voltage measures the potential difference between two conductors, while watts are a meaure of power, which means the rate at which energy is used.

In an electrical circuit the power in watts is the voltage times the current in amps.

So in a car with a 12 v system, a 6-watt bulb draws ½ an amp, while a 60 watt bulb draws 5 amps.

It is not recommended to tap into a 40 amp electric range outlet for a 15 or 20 amp wall outlet as the wiring and circuit capacity may not be compatible. It is best to consult with a licensed electrician to determine the safest and most appropriate solution for adding a new outlet.

Number 6 gauge wire typically has an ampacity rating of around 55-75 amps and a voltage rating of 600 volts. These ratings may vary depending on the specific type of wire and the regulations in your area. It is important to consult the National Electrical Code (NEC) or a qualified electrician for accurate information.

The green (or green with yellow strips) is for Earth. This is the D shaped socket in a US outlet. The Black (US) or Brown (UK) is for Live. This is the narrow rectangular socket on a US outlet. The White (US) or Blue (UK) is for Neutral. This is the wide rectangular outlet on a US socket. The color code may vary for other countries, so be sure to check.

For an 800 amp service, typically a 3/0 or 4/0 copper conductor or 250kcmil aluminum conductor would be appropriate for the grounding wire. However, it is recommended to consult with a qualified electrician or the local electrical code for specific requirements based on the installation conditions.

A 12 ga wire will overheat when you attempt to use it for a 30 amp draw.

The National Electrical Code is a well thought-out standard of engineering and the requirements are not arbitrary.

If you attempt to use 12 ga for 30 amps, you'll likely cause a fire.
