Outdoor projects require reliable electrical components that are designed to handle environmental exposure. Explore the range of outdoor wire at Ace Hardware from Southwire and other brands. Whether you are running power to a shed or setting up landscape lights, selecting the right materials can help support a successful installation.
Selecting Wire for Buried and Exterior Projects
Different environments require specific insulation and conductor types to maintain safety. Selecting the correct lighting and electrical supplies involves matching the cable rating to its intended location.
Underground Feeder (UF-B) Cable
Type UF-B cable is often used for direct burial applications where the wire is placed in the ground without a protective pipe. These cables are intended for feeder runs to outbuildings or outdoor circuits.
- Direct burial rated:The gray sunlight-resistant jacket is designed to withstand moisture and soil contact.
- Conductor options:Available in solid or stranded configurations, often featuring a ground wire.
- Installation versatility:These cables can be used for buried conduit-free installations, though cable connectors may be necessary at entry points.
THHN and Service Entrance Cable
For commercial or high-load residential needs, specific wires are used to bridge the gap between the utility source and the building. Unlike standard indoor wire, these options are built for higher capacities and specific routing.
- THHN wire:Single-conductor wires with a thermoplastic insulation that are intended for use in conduit for branch circuits or panel feeds.
- Service Entrance (SER and SEU):Multi-conductor cables typically used for utility service entrances or sub-panel feeds. Round SER and flat SEU configurations may be available depending on the project layout.
Specialized Outdoor Wiring Solutions
Some outdoor projects focus on aesthetics or specific utility functions rather than primary power delivery. These systems often operate at lower voltages or require high flexibility.
Landscape and Irrigation Wiring
Low voltage systems are common for beautifying properties and maintaining lawns. These wire types are typically easier to handle but still require weather-resistant construction.
Flexible Cords and Portable Cables
For temporary power needs or equipment, flexible cords provide the necessary mobility. When preparing these cables, using high-quality wire strippers and cutters can help provide clean connections. These cords are often oil-resistant and weather-resistant, making them suitable for outdoor power tools and appliance extensions.
Choosing the Right Outdoor Wire Type
Use the table below to compare the most common outdoor wire types by installation environment and rating.
| Wire Type | Choose If | Environmental Rating |
|---|
| Underground Feeder (UF-B) | Running power to a shed without conduit. | Direct Burial |
| THHN | Pulling single conductors through a pipe. | Heat & Moisture Resistant |
| Landscape Wire | Installing low voltage garden lights. | Sunlight Resistant |
| Flexible Cord | Powering portable outdoor equipment. | Oil & Weather Resistant |
Can You Use NM-B Wire Outside?
Non-metallic sheathed (NM-B) cable is intended strictly for interior residential wiring and should not be used outdoors. It lacks the UV-resistant and moisture-proof jacketing found in UF-B or other outdoor-rated cables. Using indoor-rated wire in exterior environments may lead to insulation degradation and electrical failure over time.
What Are the Differences Between SER and SEU Cables?
Service Entrance Cable Type R (SER) features a reinforcement tape and is typically round, containing a specific ground conductor. Service Entrance Cable Type U (SEU) is generally flat and is intended for use from the meter socket to the main service panel. Both types are stranded for easier routing during large-scale residential or commercial service connections.
