Mell How far can you run 10 gauge wire for 30 amp service?
#10 is normally used for short runs of 30 amps. With 150 feet though, I’d opt at least for #8, and maybe even #6. Go to any standard wire table to find the ohmage of the wire size. Then you can calculate the voltage loss at 30 amps and see if you can tolerate that.
How many amps can 10 3 wire take?
What Type & Gauge of Wire Should I Use?
| Type NM-B (Typical Indoor Applications)* | ||
|---|---|---|
| 10/3 with ground | Apartment size Range – up to 30 amps Built-in Single Ovens – up to 30 amps | Electric Dryer – up to 30 amps |
| 10/2 with ground | Electric Wall Heater – up to 30 amps | |
| 8/3 with ground | Double Oven Range – up to 45 amps |
How far can you run a 10 gauge wire?
How Far Can You Run 10 Gauge Wire? You can run a 10 gauge wire up to 85 feet on a 20 amp circuit. If you opt to use this type of wire on a 15 amp circuit, it can run up to 115 feet. After these distances, the circuit will go over the recommended 3% voltage drop.
What kind of cable do you need for a 30 amp subpanel?
You need 10-gauge, three-conductor cable to wire a 30-amp subpanel. This cable has two hot wires (usually colored red and black), a white neutral wire and a ground wire, which is usually bare but could be green.
What kind of wire do I need for a 30 amp circuit breaker?
The rule of thumb that techs will usually go by is that for a 30 amp circuit breaker, 10-gauge wire is the right size to go with. For a 40 amp you need a 8-gauge wire size and for a 20 amp, you will need a 12-gauge wire size.
How many amps does a 110 V breaker need?
On 110 v I believe this should be a 30 amp breaker max. There are 2 unused 20 amp 110 v circuits in the garage. I have two configurations that I can run after removing the unused circuits. One is to run another 40 feet to get to a double garage door and the other is to put a 220 outlet right by the current box which would be a bit restrictive.
What kind of ground breaker do I Need?
Simply-put, though, your city and county will have guides, and you may be able to contact a building inspector with your questions if-needed. If the rated primary current is 47 amps and the duty cycle is 20% you can use #12 thhn or #10 Romex with a 50 amp breaker.
