8 AWG THHN, 90°C copper wire is limited to 40 amperes where connected to a disconnect switch with terminals rated at 60°C. This same 8 AWG THHN, 90°C wire is limited to 50 Amp. Click to expand... Gil, This temperature you are speaking of ( the 60 and 75 degree ) is based on the terminals and conductor ratings.
However, T manual says. • If installing for less than maximum power, refer to local electrical code to select correct. conductors and ground wire size that are suitable for the chosen circuit breaker. • If installing for maximum power, use minimum 6 AWG, 90° C-rated copper wire for conductors.
The wire is conservatively sized as is, a brief inrush will not heat the wire with any noticeable difference. 50 VA does not mean 50 amps fyi. It's just a coincidence that the apparent power rating of 50 VA is the same value as the inrush current of 50 A. Didn't mean to throw you off. In rush impedance is only an issue with really high draw ...
2: Cross sectional area. The cross sectional area of a stranded and a solid conductor are the same. The effective diameter of a stranded conductor is a little bit larger than a solid conductor; look at wire strippers that have the same holes marked for different sizes depending on solid or stranded. 3: Insulation.

The problem with using #8 on a 50A breaker in residential is the 60C limitation of romex due to 334.80 as some previous posters have noted. That would limit #8 romex to a 40A breaker.
It is permissible to use a 30 amp breaker to protect 14 AWG branch circuits for A/C units. 240.4 (D) says unless specifically permitted in 240.4 (E) or 240.4 (G) the overcurrent protection shall not exceed 15 amps for 14 AWG. 240.4 (G) gives us specific conductor applications that permit larger overcurrent devices for small conductors.
Easy said: IDK 24.5 amps at 125% = 30.625 Amps = #8 wire and should be able 2 fit it all in a 3/4" run. e. You don’t need to multiply the 125% to the 24.5 , it’s already done n the nameplate. Going by the nameplate, 10 thwn and a 45a breaker to a non fused disconnect should be code compliant.
Hi all, I purchased a Comfort Zone CZ230ER 7500 Watt garage heater. The instructions say that the 7500W on a 240v circuit will require an 8 gauge wire and should be rated to 75 degrees Celsius. I want to use wire that can be run though the wall and together. I have found NM-B 8/2 wire ( 2 hot and 1 ground) rated at 60 degrees Celsius but I can ...

The only solid I use is for grounding. “I don't care that they stole my idea . . I care that they don't have any of their own”.
roundrightfarm said: I have 100 + receptacles to wire up in a house that was run completely with 12 gauge wire. Does anyone make a receptacle that allows 12 gauge to push fit into the back for a reasonable price. I've seen "industrial" rated receptacles that offer this, but they cost 5 times as much. Of course, There are plenty that take 14 in ...
