How many #12 Thhn wires are allowed in a 1/2 EMT?
Up to 11 THHN 12 AWG conductors in a 1/2″ conduit above ground have an Maximum ampacity of 20 amps.
What size conduit is needed for 10 2 wire?
1/2″ would be fine for up to 4 #10 THWN conductors (you’ll need 3). I might size up a bit just to make the pulling easier. You need to be down 18″ if you’re using sched 80 (which is advisable).
What size conduit do I need for 10 3 wire?
1/2″ EMT will be fine for up to 5 #10. You may find it easier to go up to 3/4 just to making pulling easier but it’s not required.

By National Electrical Code, 1″ EMT can handle (35) 14 gauge wires (THWN, THHN) or (26) 12 gauge wires, or (17) 10 gauge wires, or (9) 8 gauge wires, or (7) 6 gauge wires, or (4) 4 gauge wires, or (3) [3 or 2] gauge wires, or (1) [1 gauge through 4/0 or 250 mcm through 350 mcm] wire.
What is Thhn wire?
THHN is a thermoplastic high-heat-resistant, nylon-coated wire. Extremely popular as an inexpensive building wire, THHN wire serves its purpose admirably and can be used for wiring machine tools, control circuits, and certain appliances.
Does Thhn wire have to be in conduit?
You “can” run THHN wires through an attic without conduit, but such an installation would not only be dangerous but also a violation of electrical codes if the wires are then energized.

What size conduit do I need for 12 2 wire?
For two 12/2 UF, you’ll need at least 1-1/4″ conduit.
Can you run Romex in conduit?
No, you can not run your Romex wiring in conduits.
How far can I run a 10 2 wire?
The size of the wire you run to your shed depends on how far away it is and whether you use 120V or 240V. If your shed is 50 feet from your breaker box, you can use 10/2 AWG UF-B wire for a 120V circuit up to 20A. This will allow you to run multiple machines at the same time while providing light to your shed.
Are Thhn and THWN the same?
THHN stands for Thermoplastic High Heat-resistant Nylon-coated. THWN wire is the same, but the “W” stands for water-resistant. The main difference between these two standards is their maximum temperature in wet locations. However, most of these wires, so you can use THHN and THWN interchangeably.
Can you bury 10 2 wire?
Although it is rated at a conductor temperature of 90ºC dry / wet, its ampacity is limited to 60ºC according to the NEC 2008 AND NEC 2011. UF-B may be directly buried or installed where exposed to sunlight.
Can 10 3 Romex run in conduit?
The answer is a resounding yes. In fact, the National Electrical Code (NEC) calls for all non-metallic wires to be used in conduits to avoid protection from physical damage; especially if stripped.
