All NM cables are color-coded, indicating the next wire gauges and amperage (amp) rankings:
- Black: could possibly be used for 6- and 8-gauge conductors and 55- and 40-amp circuits, respectively
- Orange: with 10-gauge conductors and 30-amp circuits
- Yellow: with 12-gauge conductors and 20-amp circuits
- White: with 14-gauge conductors and 15-amp circuits
They’re simple to put in and work on. Typically, they’re utilized in frequent electrical areas corresponding to countertop retailers.
2. Underground Feeder (UF) Cables
These varieties are for moist areas, perfect for outside connections corresponding to lampposts. They comprise impartial and scorching wires sheathed in stable plastic. Typically, you can purchase UF cables with a gray cowl. Should you’re working with it, you higher watch out because it comprises a excessive quantity of voltage.
3. Thermoplastic Excessive Warmth-Resistant Nylon-Coated/Thermoplastic Excessive Warmth And Water-Resistant Nylon-Coated (THHN/THWN) Wire
These discuss with the generally used wires wrapped in plastic conduits. Typically, many electricians use THHN/THWN wires in damp areas corresponding to laundry areas since they’ve protecting properties, making them safer than the opposite cables.
If you wish to be acquainted with their sub-types, chances are you’ll discuss with the next:
- Inexperienced and yellow-green for floor wires
- White and brown for impartial wires
- Black, pink, and orange for warm wires
4. Low-Voltage Wires
These traces are used for connections with 50V or much less. Typically, they’re utilized in intercom programs, doorbells, and storage door openers. Many electricians additionally select low-voltage wires in panorama lighting and alarm programs. The wires starting from 12-22 gauges are much less prone to be concerned in main electrical shocks.
What To Take into account In Shopping for Electrical Cables
After figuring out concerning the several types of cables, chances are you’ll now think about the factors you want when selecting the appropriate cable on your wiring. For that function, listed here are a few of the qualities chances are you’ll try:
1. Sturdiness
Typically, the sturdiness of cable depends on its thickness and materials. But, there are additionally thick wires which can be unlikely simple to chop.

Nonetheless, for others, sturdiness may imply the capability to resist excessive voltage. As well as, it could additionally point out the collective resistance in opposition to excessive temperatures.
2. Materials
The cable supplies might discuss with the wire—the fabric inside the sheath or the conduit—and the sheath or conduit materials itself.
For the wire, listed here are a few of the frequent varieties:
- Copper: This kind is taken into account probably the most economical and appropriate for crimping. But, this cable might have flux when soldered.
- Aluminum: This kind is subsequent to copper relating to availability. It’s additionally lighter and straightforward to work on.
- Silver: It has better-conducting properties however is mostly costly.
- Tin: This kind protects in opposition to rusting.
For sheaths and conduits, listed here are some frequent supplies:
- PVC: It’s appropriate for under-the-ground and behind-wall purposes. It additionally melts when uncovered to excessive warmth.
- Metallic: It has a number of varieties, and every has its diploma of thickness, conductivity, and stage of safety.
- Non-Metallic: This kind has loads of options corresponding to snap locks and corrugated tubing.
Usually, the kind of materials for use ought to rely in your wiring wants.
3. Flame Retardant
In layman’s phrases, flame retardants are specific chemical substances that make merchandise like cables have higher resistance in opposition to fireplace and excessive warmth. Cables with flame-retarding properties are much less flamable in comparison with the opposite varieties. This fashion, they’re typically safer to make use of than the others.
To seek out which has flame-resistant properties, chances are you’ll learn the cable’s critiques and product particulars. You may additionally ask seasoned electricians how specific cables fare in excessive warmth. Do they soften simply? Do they snap every time an excessive amount of present flows by them? Above all, chances are you’ll attempt to decide what does lit up instantly when it caught fireplace.
4. Present Capability
Typically, cables are uncovered to excessive warmth. As well as, excessive voltage of fluctuating electrical present might harm a cable. In order for you a line that’d have an prolonged lifespan and top-notch high quality, chances are you’ll think about the way it handles sturdy present.
Despite the fact that there’s a most voltage capability in each cable sort, the power of a cable to deal with greater than what’s anticipated units it aside from different cable varieties. To decide on what may resist excessive voltage and warmth, chances are you’ll look into cable supplies with protecting protecting inside and out of doors.
Wrapping Up
Shopping for electrical cables could possibly be difficult in case you have restricted information concerning the merchandise. The great factor is you can analysis the qualities of an distinctive electrical line. Chances are you’ll look into what makes a high-quality wire by referring to the insights on this article.
