A #1 copper conductor is rated at 140 amps with an insulation rating factor of 90 degrees C at 240 volt single phase, will give you a full 100 amps at 200 feet. #4 wire should give you 95 amps. Anything over 200 feet you will start loosing more amps.

∙ 11y agoThis is a voltage drop question. A voltage value needs to be stated. Assuming that the 100 amp panel is a single phase 120/240 volt sub panel. A #1 copper conductor will limit the voltage drop to 3% or less when supplying 100 amps for 200 feet on a 240 volt system.

∙ 10y agoAWG #6 will work fine at 100 feet with only a 2% drop in voltage which is acceptable.

What size wire for 100 amp panel in detatched garage?
i just left lowes an they told me to run 100 amp to my building i would need wire size 2-2-2-4 alumninum and run it in conduit the lowes around here does not sell copper wire that size
What wire size do you need for a 125 amp panel with a 100 amp main breaker?
A #3 copper conductor with an insulation factor of 90 degrees C is rated at 115 amps. Even though the panel is rated at a higher amperage it is the main breaker that governs the wire size.
What size breaker do you use for a 100 amp sub panel?
A 100-A sub-panel would be fed from a 100-A breaker.
What size Aluminum wire is used for ground in breaker box?
For a 100 Amp breaker panel it would be 2 AWG. For 150 Amps it would require 2/0 (2 ought) aluminum wire.
Do you need a main disconnect on the feeder wires running to a detached garage running from the box in the house?
Yes you do. The detached garage will either be fed with a single circuit or a sub panel. The wire feeding the garage will need to be protected and that is the purpose of the breaker (disconnect). The breaker size will be determined by the size of the wire that is used on this circuit.
What size service cable for 100 amp main panel 100 feet away?
20Sqmm
What size aluminum wire to feed a 100 amp panel 240 ft away?
To answer this question the voltage value and whether the system is three phase or single phase needs to be given.
Is a 6 gauge 4 conductor wire still used to install a 240V 50A hot tub more than 50 ft away from the panel?
Yes, that is the correct wire gauge. However, if your tub is much more than 100 ft. from the panel you might consider going up in wire size to #4 due to voltage drop.

What size ground wire is needed for a 100 amp service panel?
#8 is the size of wire to use for grounding a 100 Amp panel. Green is color used for grounding #8 is code.
What wire size do you need for a 125 amp panel with a 100 amp main breaker?
A #3 copper conductor with an insulation factor of 90 degrees C is rated at 115 amps. Even though the panel is rated at a higher amperage it is the main breaker that governs the wire size.
Can you install a 150 amp meter base and still have a 100 amp main panel?
The wire size in a meter stack is governed by the size of the first over current device.
What size conductors to run 100 amp sub panel 300 foot away?
120v ac at 100 " the wire is 000 AWG or BS longer length above it is unsafe. IS THERE A SOLUTION SURE 4 wires 0000 at 40 amps will do it for 110v single phase.
What size of ground wire for a bank of 3 one 100 amp panels?
#8 would be fine if you ground each panel separately to the ground rod
Can you tap off of a 200 amp service for 2 100 amp panels?
Yes, but at every reduction in wire size there has to be a breaker sized to the smaller wire size. The wire size for 100 amp panels is recommended at #3 copper conductor. From the 200 amp feeder panel you will require a 100 amp two pole breaker for each of the two 100 amp services. Keep in mind that if you run the 100 amp services close to maximum this will take away the capacity of the 200 amp service for other branch circuits coming off of it. Also keep in mind that if the panels are located, not in the same building as the 200 amp service that the 100 amp panels will be treated as separate services and will have to be constructed like a 100 amp service. This includes ground rods. Also the bonding screw will have to be removed that connects the neutral buss to the panel enclosure.
What size breaker do you use for a 100 amp sub panel?
A 100-A sub-panel would be fed from a 100-A breaker.
What size wire do you need for 100 amp feeder single phase running 350' away?
To answer this question a voltage must be given.
