Customer Questions & Answers

How much does this full spool weigh?

Is this the same as 2/0 copper wire?

Is this the same as 2/0 copper wire?
Asked by: Rufus
No, 2/0 is the 'same' as 00 wire. This is #2AWG. 2/0 is much larger (in diameter) than #2 and therefore is used for much larger applications requiring much higher load (ampacity) rating. Please note that working with loads requiring either wire size is extremely dangerous (lethal). Examples per use, #2AWG could be used to wire a smaller sub-panel whereas 2/0 wire could be used in a main service panel. You can look up the ampacity rating for the wires online to determine which size wire is appropriate for the application.

is this 2-gauge (AWG)?

2 STRANDED THHN BLACK (BY-THE-FOOT) - It does not actually say what gauge this wire is. Please confirm. If it is 2-gauge, you should probably state that in the specifications.
Asked by: timeklund1
The fourth line, left column, under "Details", now says this is "2" gauge.

Is this #2 wire what i would use to connect a small breaker box to my main breaker box in another part of my house?

Asked by: Logan
THHN cannot be used in residential applications. The above advice is based upon the current edition of the National Electric Code (NEC). Free access to the latest version of the NEC is available online at The NEC and local building codes regulate the types of wire and cable that can be used in specific electrical applications, as well as the manner of installation. Check your local building codes before you start any wiring and cable electrical project and be sure to obtain required permits. When your work is complete, always have it inspected for compliance with local codes to ensure that it has been safely installed.
