Types of Wire, Cords & Cables We Supply

THHN / THWN Building Wire

Single-conductor wire for conduit and raceway installations — THHN for dry locations, THWN for wet or damp locations. The most common choice for commercial and industrial branch circuits.

Romex (NM-B) Cable

Non-metallic sheathed cable bundling multiple THHN-type conductors in a single PVC jacket — the standard for dry, indoor residential wiring.

XHHW Wire

Cross-linked polyethylene insulation built for commercial and industrial applications, with strong resistance to heat and moisture.

Bare & Stranded Copper Wire

Grounding and bonding conductors for panels, equipment, and structures, available in a range of gauges.

Cords & Cord Sets

Extension cords, power cords, and portable cord assemblies for jobsite, industrial, and facility use.

Coaxial & Low-Voltage Cable

Coaxial and control cable for data, video, and low-voltage wiring — paired with our DataComm product line for complete installations.

THHN vs. Romex vs. XHHW: What’s the Difference?

The wire gauge needed for a given circuit — for example, 12 AWG copper for a standard 20-amp circuit — stays the same across THHN, XHHW, and Romex, since ampacity is set by conductor size, material, and temperature rating rather than insulation type. What changes is where each type is used: Romex (NM-B) bundles several conductors in one PVC jacket and is built for dry, indoor residential wiring. THHN is a single conductor used in conduit for commercial and industrial branch circuits in dry locations, while its wet-rated counterpart THWN handles damp or wet environments. XHHW uses cross-linked insulation and is common in larger commercial and industrial installations where extra heat and moisture resistance is required.

Frequently Asked Questions

What is the difference between THHN and Romex wire?

THHN is a single conductor typically installed inside conduit, while Romex (NM-B) is a cable that bundles several THHN-type conductors together in one non-metallic sheath for dry, indoor residential wiring. Romex is essentially multiple THHN wires combined under one jacket.

What gauge wire do I need for a 20-amp circuit?

A standard 20-amp circuit typically uses 12 AWG copper conductors, whether you’re using Romex, THHN, or XHHW — the gauge requirement is the same across wire types because ampacity is based on conductor size and temperature rating, not insulation type. Always confirm the exact requirement with your electrician or local code.

Can I use THHN wire outdoors or in wet locations?

Standard THHN is rated for dry locations only. For wet or damp environments, use THWN-rated wire (often dual-rated as THHN/THWN) or XHHW, which are built to handle moisture exposure.

Does ATEK sell wire in bulk reels for large projects?

Yes. We supply THHN, XHHW, Romex, and bare copper wire in bulk and reel quantities for commercial, industrial, and government projects, in addition to smaller contractor orders.

What's the difference between copper and aluminum wire?

Copper has higher conductivity and is the standard for most branch circuits, while aluminum is lighter and less costly for larger gauge, high-amperage runs but requires larger gauge sizing and anti-oxidant compound at terminations. Your electrician or engineer specifies which is appropriate for a given run.

Can ATEK supply wire for government or commercial contracts?

Yes. ATEK Distribution is a certified SDVOSB and GSA Contract Eligible Supply Partner, active in SAM.gov, supplying wire, cords, and cable to federal, state, and municipal agencies as well as commercial contractors nationwide.
