Planning Your Outdoor Electrical Outlet Post Installation

When planning to install an outdoor electrical outlet post, several factors must be considered to ensure safety, functionality, and compliance with local codes. Let’s break down the key aspects: location, height standards, ground clearance, and weatherproofing.


Choosing the right location is crucial. Here are some tips:

  • Distance from Water: Ensure the outlet post is at least six feet from any water sources, such as pools or fountains. This minimizes the risk of electrical hazards.
  • Accessibility: Place the outlet where it will be easily accessible for its intended use, whether for powering garden tools, lighting, or outdoor appliances.
  • Avoid Obstacles: Steer clear of tree roots and other underground obstacles when planning your conduit path.

Height Standards

Proper height ensures the outlet is convenient and safe to use. The National Electrical Code (NEC) provides guidelines:

  • Standard Height: Outdoor outlets should be installed at least 12 inches above ground level to prevent water ingress.
  • Custom Heights: Depending on your needs, you might install outlets at different heights. For instance, outlets for holiday lighting might be higher up on posts or walls.

Ground Clearance

Ground clearance is about ensuring the outlet is safe from water and debris:

  • Minimum Clearance: As mentioned, maintain at least 12 inches of clearance from the ground.
  • Flood Zones: In areas prone to flooding, consider mounting the outlet higher to avoid water damage.


Weatherproofing is essential to protect the outlet from the elements:

  • Weatherproof Boxes: Use weatherproof outlet boxes and covers. These are designed to keep moisture out and protect the electrical components.
  • GFCI Protection: Ground Fault Circuit Interrupter (GFCI) outlets are a must for outdoor installations. They protect against electrical shock by shutting off the power when an imbalance is detected.
  • In-Use Covers: These covers allow you to keep the outlet protected even while it’s in use. They are ideal for continuous use scenarios, such as holiday lighting or pond pumps.

Pro Tip: Always use IP-rated enclosures for outdoor outlets. IP ratings indicate the level of protection against dust and water. For instance, an IP65-rated enclosure is dust-tight and protected against water jets.

By planning your installation with these factors in mind, you ensure a safe, functional, and durable outdoor electrical setup. Next, we’ll dive into choosing the right materials for your installation.

Choosing the Right Materials

When installing an outdoor electrical outlet post, selecting the right materials is crucial for safety and durability. Let’s break down the key components you’ll need.

NEMA Connectors

NEMA connectors are the standard for electrical outlets and plugs in North America. They come in two basic types: straight-blade and locking. For outdoor use, locking types (prefix “L”) are often preferred for their secure fit, which prevents accidental disconnections.

Example: The 5-15R is a common 125V, two-pole, three-wire receptacle rated for 15A. For a more secure connection, consider the L5-15R locking design.

Weatherproof GPO

A Weatherproof General Purpose Outlet (GPO) is essential for outdoor installations. These outlets are designed to withstand various environmental conditions like rain, snow, and sunlight. They often come with waterproof covers and gaskets to keep moisture out.

Tip: Always look for outlets labeled as weatherproof or IP-rated to ensure they can handle harsh weather conditions.

UV-Rated Plastic

Outdoor electrical components are exposed to sunlight, which can degrade materials over time. UV-rated plastic is designed to resist the damaging effects of UV rays, ensuring your outlet post remains durable and functional for years.

Fact: Many customers appreciate the quality and sturdiness of UV-rated plastic materials, mentioning that products made from these materials are well-built and long-lasting.

In-Ground vs. Surface Mount

Choosing between in-ground and surface mount installation depends on your specific needs and the layout of your outdoor space.

  • In-Ground: These posts are buried into the ground, providing a stable and permanent installation. Ideal for areas where you want a clean look without visible mounting hardware.

  • Surface Mount: These are attached to a flat surface like a deck or concrete slab. They are easier to install and move if needed but may not be as stable as in-ground posts.

Customer Insight: A user mentioned, “It’s sturdy when installed into solid ground. I will reserve the 5-star rating until I see how this post holds up to soccer balls and kids.”

Additional Considerations

  • Ground Fault Circuit Interrupter (GFCI) Outlets: Essential for preventing electrical shocks. Ensure your outdoor outlet is GFCI protected.

  • Bubble Covers: These covers protect the outlet even when in use, keeping moisture out.

By choosing the right materials, you’ll ensure your outdoor electrical outlet post is safe, durable, and functional. Next, we’ll guide you through the step-by-step installation process.

Step-by-Step Installation Guide

Back-to-Back Installation

Back-to-back installation is one of the simplest methods for adding an outdoor outlet. This involves installing the new outlet directly opposite an existing indoor outlet. Here’s how you do it:

  1. Locate the Indoor Outlet: Identify an indoor outlet that is close to where you want your outdoor outlet.
  2. Drill a Hole: Carefully drill a hole through the wall behind the indoor outlet.
