| Rating or setting of Automatic Overcurrent Device (OCPD) in Circuit ahead of Equipment [i.e Circuit Breaker]. Not exceeding (Amps) | Size (AWG or kcmil) | |
|---|---|---|
| 20 | 12 | 10 |
| 30 | 10 | 8 |
| 40 | 10 | 8 |
| 60 | 10 | 8 |
Can I use #12 for ground wire?
The conduit can still be used as a grounding conductor, but if you choose to put in a Grounding wire it must be sized to the Overcurrent protection. EMT is not an acceptable ground. Rigid conduit is, but EMT is different and yes you must run a #12 ground with #12 conductors.
Can you use 12 gauge wire for a water heater?
Common Current and Wire Gauge Sizes
Wire a hot water heater with wire that’s sized to accommodate the heater’s current requirement. For example, a 20-amp hot water heater needs 12-gauge wire, a 25-amp hot water heater requires 10-gauge wire, and a 30- to 40-amp hot water heater requires 8-gauge wire.
What size ground wire do I need for a 60 amp sub panel?
I would double check the wire size a 60 amp breaker will require #10 for the equipment grounding conductor per NEC table 250.122.
How do I know what size ground wire to use?
For sizing a grounding electrode conductor (GEC) for a single service, the grounding electrode conductor is required to be sized in accordance with 250.66 and Table 250.66. That conductor is required to be a minimum size of 8 AWG copper and need not be larger than 3/0 AWG copper.
What size ground do I need?
Table 250.122 Minimum Size Equipment Grounding Conductors for Grounding Raceway and Equipment
| Rating or Setting of Automatic Overcurrent Device in Circuit Ahead of Equipment, Conduit, etc., Not Exceeding (Amperes) | Size (AWG or kcmil) | |
|---|---|---|
| Copper | Aluminum or Copper-Clad Aluminum* | |
| 20 | 12 | 10 |
| 60 | 10 | 8 |
| 100 | 8 | 6 |
What is 12 AWG wire used for?
12-gauge are used in kitchen, bathroom, outdoor receptacles, and 120-volt air conditioners supporting 20 amps. 10-gauge are used in electric clothes dryers, 240-volt window air conditioners, electric water heaters supporting 30 amps.
How many amps can 12 gauge wire handle?
20 amps
“Twelve-gauge wire is good for 20 amps, 10-gauge wire is good for 30 amps, 8-gauge is good for 40 amps, and 6-gauge is good for 55 amps,” and “The circuit breaker or fuse is always sized to protect the conductor [wire].”
What happens if ground wire is too small?
With too-small a ground wire, the breaker cannot magnetic-trip because it cannot flow enough current to hit 10x, because of the too-high resistance of the wire.
What size ground do you need for #6 wire?
12 AWG
According to the new code language, if the 6 AWG conductor is connected to a 20-amp overcurrent device, the minimum required size copper equipment grounding conductor (12 AWG per Table 250.122) can still perform to carry 20 amps of ground fault current under these circumstances.
What size ground do I need for 50 amps?
Your conductors need to be 6awg and your ground needs to be 10awg per nec code for a 50a circuit. Sizing a neutral is a bit more complicated on size reductions, and is generally not a good idea when wiring receptacles as you are not always sure what might get plugged in.
What wire do I use for a 60 amp breaker?
For 60 ampere breakers, electricians and professionals suggest using a wire size gauge ranging from 6 AWG to 4 AWG.
Can you downsize ground wire?
For ground wire, the size can either be smaller or bigger sometimes.
What is the minimum size grounding conductor for a piece of equipment with a 50 amp circuit breaker?
The equipment grounding conductor based on Table 250-122 for the 50-ampere range circuit is a No. 10 copper or No. 8 aluminum.
What size ground wire do I need for a 70 amp circuit?
If you really want 70A, then again THWN in conduit gives you an advantage as this only requires #6 copper or #4 aluminum conductors and a #8 ground. (cable would require a size bump). If you go #3 copper or #1 aluminum you are good for 100A with a #8 ground. (Above 100A you’ll need #6Cu or #4Al ground wire).
Do you upsize ground wire for voltage drop?
EGCs are required to be increased in size to address voltage drop. In addition, a proportionate increase of the associated ungrounded circuit conductors is required.
What wire do you use for 50 amps?
6
50 AMP Wire Size
For a maximum of 50 amps, you’ll need a wire gauge of 6. Fifty amp breakers are most often used to power many different appliances.
Can you double up 12 gauge wire?
#12 AWG is protected by a 20A fuse. Doubling #14, 12, 10, 8, ……wire to increase ampacity is not allowed. Doubling is allowed for much larger sizes.
Will a 12 2 wire carry 30 amps?
Yes, based on the National Electric Code or NEC, you can use 12-2 AWG cables for THHN or THWN-rated wires. These cables are made for general purposes and can hold up to 194 degrees without taking any damage. It simply means these wires can withstand the heat temperature drawn by a 30 amp circuit breaker.
