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.
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.
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.
What can you run on a 400 watt inverter?
Four 100 watt light bulbs or anything else that sums to 400 watts.
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).
What size ballast do you need for a 430 watt high pressure sodium bulb?
430 watt bulbs are made to juice a little more light from a standard 400 watt ballast. you get about 3-5000 more lumens. A typical 400 watt HPS produces about 50-55,000 lumens. The 430 will put out about 58,000. Not a lot, but a little extra without any increase in power usage.
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.
Will a 600 watt amp be any louder then a 400 watt amp with 400 watt woofers?
It will, but only 1.75 decibels louder. The smallest change in loudness that most people can detect is 1 decibel, so the difference between 400 and 600 watts would be barely noticeable.
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
How many 100 watt bulbs is equal to one 400 watt bulb?
ummm...4(?) is this a trick question?
