150 Amp Service Ground Wire Size. What is the right wire size for 100 amp service 150 feet distance? Assuming this falls under the national electrical code (nec) the size for the service ground is based on the conductor size of the ungrounded (hot) conductors.
The ground wire is copper in most homes and is #6 (6 awg) or larger. The nec establishes a limit on how many amps can safely pass through a wire of a particular gauge. However, you cannot use a smaller wire.

The Ground Wire Is Copper In Most Homes And Is #6 (6 Awg) Or Larger.
The ground wire size for 70 amp is 4awg. The 2014 version allowed you to size the conductors to 83% of the service rating, which usually worked out to about the same as the old table. For 150 amps in thwn wire size is 1/0, some municipalties allow you to go 1 size smaller, since it carries the unbalanced load, and that would be a #1.
That Conductor Is Required To Be A Minimum Size Of 8 Awg Copper And Need Not Be Larger Than 3/0 Awg Copper.
You can use a larger conduit if necessary to maintain the inner fill of 40% or less. Rating or setting of automatic overcurrent device in circuit ahead of equipment, conduit, etc. You can also use 6awg copper wire or 4awg aluminum wire.
Each Bus Bar Carries 120 Volts.
110 amps #3 awg #1 awg: 150 amps #1 awg #2/0 awg: The ground wire is a defensive component that directs the current to the earth when a malfunction occurs.

150 ampere x 0.83 = 124.5 table 310.15 (b) (16) says that 1 awg copper is good for 130 amperes at 75c. A ground rod needs to be at least 5/8″ (0.625) in diameter and at least 8 to 10 feet long with a clamp and the appropriate ground wire. However, you cannot use a smaller wire.
Where Not Protected, 6 Awg Grounding Electrode Conductor Shall Closely Follow A Structural Surface For Physical Protection.
The work and materials are very similar between 150 and 200 amp. (read light bulb socket sizes chart) what size of ground wire is needed? You’ll need to consider a few things when selecting your wiring, including your personal preferences, the voltage drop, and the length of the wire.
