Reading the print

What the Letters on the Jacket Mean

Wire type is the thing people most often get wrong on an order, and it's the one that fails an inspection.

Type	Where it's used	Watch for
THHN	Individual conductors pulled in raceway, dry and damp locations	Dry/damp only — not rated for wet locations on its own
THWN / THWN-2	Same, but rated for wet locations	The -2 suffix is the one rated 90°C wet as well as dry
NM-B (Romex)	Interior branch circuits in dry locations	Ampacity limited to the 60°C column regardless of the conductor rating
MC / armored	Where a jacketed cable needs physical protection	Fittings must be listed for the specific cable type
XHHW-2	Feeders and larger conductors; standard on aluminum building wire	Larger outside diameter than THHN at the same size — check conduit fill

Most copper building wire sold today is dual- or multi-rated and the surface print tells you exactly what it is — read the print rather than trusting the bin label. Our guide to THHN, THWN and THWN-2 goes through the letters one at a time.

Built for the job

Materials You Buy Most, Priced for the Trade

Wire is a commodity right up until you need a specific gauge in a specific colour on a Tuesday morning. That's what a counter is for.

Send a Cut List

Cut to length. Tell us the footage and we'll cut common wire and cable rather than selling you a full spool you don't need.
Colour on hand. Say which colours and gauges the job calls for when you send the list — it saves a second trip.
Conduit and fittings together. EMT, PVC and flex alongside the boxes, connectors and straps from Cantex, Orbit and Arlington, so the whole run comes off one order.
Feeder and service sizes. Larger THHN/THWN for feeders and service work, quoted by the foot.
Special order. Unusual gauges, colours or specialty cable — send the spec and we'll source it.

Sizing a feeder? Start with our guide to wire size for a 100 amp subpanel — it walks through the ampacity table, termination ratings and the derating that catches people out.

Common questions

Frequently Asked Questions

What wire gauges do you stock?

Common building-wire gauges in THHN/THWN, plus Romex and MC cable. If you need a specific gauge or color, ask and we will confirm availability or source it.

Do you cut wire to length?

Yes, we cut common wire and cable to the lengths your job needs.

Do you carry conduit and fittings?

What is the difference between THHN and THWN?

THHN is rated for dry and damp locations; THWN adds a wet-location rating, and THWN-2 is rated 90 degrees Celsius in both wet and dry. Most copper building wire sold today carries more than one rating — read the surface print on the conductor.
