FAQ
Is 14mm² THHN the same as 14 AWG THHN?
No, they are vastly different. 14 AWG is a small wire (2.08 mm²) for lighting. 14mm² is a large cable, roughly equivalent to 6 AWG (13.3 mm²). It is used for sub-mains and heavy equipment. Confusing these two can lead to dangerous overloading.
What is the ampacity (current rating) of 14mm² THHN?
According to standard metric tables (e.g., PEC/IEC), 14mm² THHN is typically rated for 75 Amps at 75°C and up to 90 Amps at 90°C in dry locations. It is commonly protected by a 60A or 70A circuit breaker depending on the terminal temperature rating.
Can I use 14mm² THHN for a residential service entrance?
Yes, for smaller services. It is often used as the service entrance wire for small apartments or as a sub-feeder to a secondary distribution board.
