As always, if you are in doubt about what to do, the best advice anyone should give you is to call a licensed electrician to advise what work is needed.
Before you do any work yourself,
on electrical circuits, equipment or appliances,
always use a test meter to ensure the circuit is, in fact, de-energized.
IF YOU ARE NOT ALREADY SURE YOU CAN DO THIS JOB

What else can I help you with?
How do you convert to watts to horsepower?
To convert Watts (W) to a horsepower rating (HP) simply multiply the Watts by 0.00134 W x 0.00134 = HP
How do you calculate the watts of a central air and heat unit?
You should not have to calculate the watts of the unit. All the information that you need will be on the nameplate of the unit. It is this information that electricians use to calculate the conductor size and breaker to supply the power to the unit.
How do you calculate power dissipated by an IC?
It is very critical to never exceed the input voltage of an IC to begin with. To calculate the power dissipation ( in watts) VxI (Voltage x Current) will give you power in watts.
Calculate the power in watts used if you exert 50 joules of work in 5 seconds?
Watts is joules per second, so 50 joules in 5 seconds is 10 watts.
Calculate watts for a 4160 volt 55 amp 80 power factor 3 phase motor?
317.025280 KILOWATTS = 317,025.28 WATTS
What is the service demand for two 15000 watt ranges?
Use this formula Amps = Watts/Volts.
What is the correct formula to calculate a fuse rating?
watts Divided by Volts = amps
What is the amp rating for a 2kw fan heater?
To calculate the amp rating for a 2kW fan heater, divide the power rating (2000 watts) by the voltage of your electrical system. For example, in a 120V system, the amp rating would be around 16.67 amps (2000 watts / 120 volts).
How do you calculate power load given kva?
If you multiply kVA by Power Factor (Ranges from zero to one) you get watts which is effective power.
How can you calculate the current an appliance can use?
To calculate the current an appliance can use, divide the power rating of the appliance (in watts) by the voltage it operates on (in volts). The formula is: Current (in amperes) = Power (in watts) / Voltage (in volts). This calculation will give you the maximum current the appliance can draw under normal operating conditions.
Can you use 20 watts or 30 watts in a fuse?
No, watts are a measure of power while fuses are rated in amperes (amps). To determine the fuse rating, you need to calculate the current in amps by dividing the power in watts by the voltage. Then, choose a fuse that is rated equal to or slightly higher than the calculated current in amps.
How do you figure watts for 8 Ohm speakers?
The power rating of speakers has nothing specific to do with ohms. look at the Watts rating printed somewhere on the speakers
What is the VA rating for common appliances?
For all intents and purposed the VA rating is the same as the wattage rating of appliances. VA is an electrical classification for Volt Amps. The formula for watts is, Watts = Amps x Volts.
How much watts in 16kv?
To calculate the watts in 16kV, you would need to know the current flowing through the circuit. The formula to calculate watts is Watts = Volts x Amps. Without the value of current (Amps), we cannot determine the watts.
Why maximum demand rating is not expressed in kw?
maximum demand is measured in kva because current drawn is dependent on power factor for the same load and current drawn is calculated with kva
2 500 watt lights 100ft extension cord calculate amps?
To calculate the amperage, use the formula: Amps = Watts / Volts. Assuming standard US voltage of 120V, the total power consumption of the lights is 1000 watts. Thus, Amps = 1000 watts / 120 volts = 8.33 amps. Be cautious not to exceed the extension cord's amperage rating to prevent overheating and potential fire hazards.
How can a power rating be used to calculate electricity used?
A power rating indicates the rate at which electrical energy is consumed by a device. To calculate the electricity used, multiply the power rating (in watts) by the time the device is in use (in hours), and divide by 1000 to convert to kilowatt-hours. This formula gives the total electricity consumption of the device.
