To answer this question a voltage needs to be stated. The formula needed to find the amperage is I = W/E. Amps = Watts/Voltage. Once the amperage is found, the proper size conductor to handle that current can be established. Without knowing the amperage on 400 watts a good guess would be a #14 wire. This wire size is good up to 1440 watts at 120 volts.

What wire size for 400 amp service neutral size?
You need to look at the regulations that apply in your country. If in doubt, use a neutral wire of the same size as the live wire or wires.
How many 400 watt metal halide lamps will operate off a 1000 watt ballast?
It will power two 400 watt lamps.
What gauge wire to use for direct burial for a garage that is 400 feet from your house?
Depends on the size of the sub-panel in that garage. If you are installing a 60 amp sub-panel 400 feet away from the main service panel then use AWG # 4.
What size conduit and aluminum wire for a 400 foot run on a 120 240 volt system?
The key parameter in sizing wire is the current requirement. Once you know that you can look up value in a wire gauge table. The length of the run is important for longer runs because of the resistance of the wire itself. Aluminum wire requires a larger diameter than copper for the same current. Once you calculate the wire size you can then size the conduit.
What is the weight of 400 mcm copper wire per foot?
500mcm 37 strand copper wire = 1.544lbs/ft.
How many BTU in 400Watt hours?
To convert 400 Watt hours to BTU, you need to multiply by 3.412 to get the energy in BTU. So, 400 Watt hours is equivalent to approximately 1364.8 BTU.
What wire size for 400 amp service neutral size?
You need to look at the regulations that apply in your country. If in doubt, use a neutral wire of the same size as the live wire or wires.
How many 400 watt metal halide lamps will operate off a 1000 watt ballast?
It will power two 400 watt lamps.
What size wire do you use and do you need a 240 volt sub panel to send power to some lights and a 1500 watt 120 volt heater about 400 feet away?
For a 1500 watt 120 volt heater located 400 feet away, you would need to use at least 10-gauge wire to minimize voltage drop and ensure efficient power transmission. It is recommended to install a 240 volt sub panel near the heater location to account for the distance and potential power requirements for additional lights or equipment.
How much is 400 Wh inn Joules?
1 Joule is 1 Watt-Second. 1 Watt Hour is 3600 Watt-Second or 3600 Joules. 400 Watt-Hours is 1440000 Joules.
How many 100 watt bulbs is equal to one 400 watt bulb?
One 400 watt bulb is equivalent to four 100 watt bulbs in terms of total power output.
How many lumens do you need to replace a 400 watt halogen with a led flood light?
From halogen to LED you can divide by 4 to find the equivalent. Therefore an 80 watt LED would do the job.
How many units of electricity does a 400 watt bulk use in an hour and how much?
Per hour the answer is 400 watt-hours or 0.4 kW-hours (or units).
4 250 mh bulbs 1 1000 watt mh ballast how to wire?
I would wire them together in a parellel circut. all the lights together, white to white black to black then put your ballast to em. it works like that with my 400 watt mh/hps ballast and 2 250 watt hps bulbs. run 2 hps bulbs with 2 mh bulbs if you can, you get better results.
Watt are 4 wheel puns?
The solar component for a 10 watt system can be had for under $400 USD.
If you buy a two sub woofers with 400 Watt continuous and 1200 watt peak power how many watt amp should you buy?
800 watt should be fine
What size ballast do you need for a 430 watt high pressure sodium bulb?
For a 430 watt high pressure sodium bulb, you would typically need a ballast that is rated for 400-430 watts to properly operate the bulb. It is important to match the wattage of the bulb with the wattage rating of the ballast to ensure optimal performance and lifespan of the bulb.
