This adjusts based on the above factors and environmental changes. 100 amp service 150 feet away from the sub panel requires #00 awg wire (also known as 2/0 awg wire). If you are calculating full load then the grounding conductor must take voltage drop into account and rise a full two sizes more just like the current carrying conductors or a #4 cu or #2 al. From nec 250.122 this requires an #8 cu or #6 al ground wire as a minimum (or 6cu and 4 al if you are really running a 110amp feeder). Web your 1awg al is good for a 100 amp feeder (actually 110). Generally, the wire that is suitable to run a 100amp subpanel is #4 copper wires or #2 aluminum wires. Web a 100a breaker would require a #8 cu or a #6 al. Web for sending 100 amps current 150 feet away, we need a wire with at least 162.5 ampacity. Web installing a 100 amp sub panel needs a #4 awg copper wire or #2 awg aluminum or. We’ll discuss these issues below.
A lower gauge is generally safer than higher gauges. If you are calculating full load then the grounding conductor must take voltage drop into account and rise a full two sizes more just like the current carrying conductors or a #4 cu or #2 al. Source if you want to use aluminum, you need at least #2 gauge or perhaps #1. From nec 250.122 this requires an #8 cu or #6 al ground wire as a minimum (or 6cu and 4 al if you are really running a 110amp feeder). A lower gauge is generally safer than higher gauges. We’ll discuss these issues below. Web 100 amp sub panel wire size: Web a 100 amp subpanel typically requires 6 awg copper wire (or 4 awg aluminum wire) and 10 awg copper wire for the grounding circuit. Web a 100a breaker would require a #8 cu or a #6 al. Web a 100 amp sub panel wiring size requirement is #4 for copper wires and #2 for aluminum wires. Web installing a 100 amp sub panel needs a #4 awg copper wire or #2 awg aluminum or.
