- Understanding the 75°C vs 90°C column in Ampacity Table. . .
The columns indicate how much amperage is required to raise the temperature of that size conductor to that column's temperature under standardized conditions So a 2 0 XHHW will reach 75°C at 135A and 90°C at 150A The wire insulation is good for 90°C, so for sizing the wire, we can use the
- High bays hanging from rigid conduit - Electrician Talk
My AI NEC assistant tells me this is permissable Yes, the National Electrical Code (NEC) allows luminaires (light fixtures) to be supported by a chain from a rigid conduit under specific conditions
- Branch Circuits - Electrician Talk
Branch circuits The distinction between a branch circuit and a feeder can be a source of confusion for the Code user The first step in eliminating this confusion is to understand that the NEC defines a branch circuit as “the conductors between the branch-circuit final overcurrent device protecting the circuit and the outlets” (such as receptacles or lights) [Article 100]
- Ground rod horizontal in ditch - Electrician Talk
Grounding in NEC has become a cruel joke It’s like tge stupid 25 ohm maximum rule, OR just use 2 rods Granted the Earth electrode isn’t as critical as they make it out to be, or they would just stop with saying 25 ohms or less and basically we don’t care how you get there I’m not a fan though of anything but a single point ground rod
- Table 300. 5 interpretation - Electrician Talk
For a given column of Table 300 5 ("minimum cover requirements") there is a potential overlap of the various rows The one that concerns me at present is Column 2 (IMC and RMC conduit) If it's buried in a trench below 2" of concrete or equivalent, but also goes under a parking area in a
- NEC Requirements for Generators and Standby Power Systems
NEC Requirements for Generators and Standby Power Systems Rule 220 87, Articles 445, 700, 701, and 702
- 210. 8 (F) Outdoor Sauna 2023NEC - Electrician Talk
I am mainly looking for opinions here I feel best leaving GFCI protection installed however in the eyes of the NEC would 210 8 (F) apply since the “outlet” is the heater which is located INSIDE of the structure?
- Line load same conduit - Electrician Talk
Is it against nec to run line and load in the same conduit to A fused 30 amp disconnect ? Running line and load in the same conduit is generally fine as long as it's rated for the ampacity and meets NEC requirements Proper separation and conduit fill calculations are key to avoid overheating I was unsure about ordering a paper online, but my classmate told me to check the DoMyPaper samples
