Supplementary Common Specifications

Material: The entire series uses new ABS material or ABS+PC, featuring impact resistance (withstanding minor outdoor collisions), UV aging resistance (preventing brittleness from sun exposure), and chemical resistance (tolerating corrosive substances in soil/rainwater). The surface is smooth and easy to clean.
Protection Rating: Uniformly rated IP65, which can completely block dust and splashing water. Combined with polyamine gaskets, it is suitable for scenarios such as heavy rain and humid underground environments.
Internal Structure: All models have built-in ≥2 M4 copper nuts and reserved mounting positions for circuit boards/DIN rails, allowing direct fixing of terminals or circuit boards without additional accessories.

III. Core Functions & Advantages

1. Weather Resistance & Protection: Adaptable to Harsh Outdoor/Underground Environments

Full-Scenario Protection: IP65 rating + polyamine gaskets can resist heavy rain, dust, and splashing water. When buried underground, it also blocks soil moisture and microbial erosion, preventing circuit short circuits.
Aging Resistance Design: UV stabilizers are added to the material, ensuring no obvious aging after over 2,000 hours of outdoor sun exposure. It does not become brittle or deform in the extreme temperature range of -20℃ to +80℃, adapting to winter in northern regions and high-temperature environments in southern regions.

2. Structural Adaptability: Balancing Convenience & Practicality

Flexible Opening/Closing: Adopts a snap-on/flip-top design, allowing quick opening without tools, which improves the efficiency of later wiring maintenance (e.g., inspection and repair of landscape lighting lines).
Multi-Wire Management: The box body has reserved multiple sets of wire inlets and supports customized hole drilling (to fit wires of different diameters, such as 10mm landscape wires and 16mm power cables). Sealing can be further enhanced by matching with waterproof cable glands to avoid messy wiring.

3. Flexible Installation: Covering Both Above-Ground & Underground Scenarios

Above-Ground Installation: Through pre-reserved screw holes on the base, it can be directly fixed to walls, wooden boards, metal plates, etc., using ordinary screws/nails, and can be operated by a single person.
Underground Installation: The material is resistant to soil pressure and erosion, and can be directly buried 10–15cm deep in the soil, suitable for protecting underground cables in gardens and driveways without additional reinforced brackets.

4. Cost & Compliance: High Cost-Effectiveness + Global Adaptability

Cost Advantage: The unit price of small models is as low as $7.28, suitable for individual DIY purchases; although large models have higher prices, they are 50% lighter than metal junction boxes (reducing transportation/installation costs) and free from rust risks, offering higher cost-effectiveness for long-term use.
Global Compliance: Complete CE, ROHS, and IEC60439 certifications eliminate concerns about regional installation standard restrictions, making it suitable for both export and domestic commercial scenarios.

IV. Main Application Scenarios

Based on the core characteristics of "large size, strong protection, and multi-installation methods," the series accurately covers four fields, with clear function-matching logic for each scenario:

Application Field	Specific Scenarios	Adaptation Advantages
Outdoor Landscape Engineering	Courtyard/commercial landscape lighting control, sprinkler system wiring	IP65 waterproof + UV resistance; small models offer good cost-effectiveness, suitable for wiring in green environments
Underground Power Protection	Garden/driveway underground cable branches, commercial landscape buried lines	Soil erosion-resistant material + sealed design, preventing line damage from groundwater/microorganisms
Commercial Outdoor Power Distribution	Outdoor power panels, large factory outdoor power distribution nodes, airport/port outdoor lines	Large models (600×400×220mm) have sufficient capacity, suitable for complex power distribution with multiple lines
DIY & Home Projects	Home Depot-style outdoor wiring (e.g., patio lights, lawn lights)	Small models are easy to install and support customized hole drilling, adapting to individual construction capabilities

In addition, it can also be used for "outdoor power distribution in public facilities" (e.g., street lamp control boxes) and "outdoor equipment in small-to-medium businesses" (e.g., power supply for outdoor advertising screens), offering strong scenario extensibility.

Q1. Can you put a PS-GT series junction box for underground electrical wires?

Yes—the PS-GT series is well-suited for protecting underground electrical wires (e.g., garden irrigation cables, driveway sensor lines) thanks to its soil-resistant design and waterproof performance:

Burial-ready material: The series’ ABS/PC plastic is resistant to soil corrosion, microbial damage, and underground moisture—unlike metal boxes that rust or degrade in damp soil. Medium-to-large models (e.g., 500×400×200mm or 600×400×220mm) are recommended for underground use, as their thicker shells (5-6mm) tolerate soil pressure better.

Waterproof guarantee: With an IP65 rating and polyamine gaskets, the box blocks groundwater seepage even when buried 10-15cm deep (the recommended burial depth). For extra protection, pair it with waterproof cable glands (via the PS-GT’s custom drilling service) to seal wire entry/exit points—preventing soil particles from entering the box.

Installation tip: Avoid burying the box in low-lying areas (to prevent standing water accumulation). Add a 5cm layer of gravel beneath the box to improve drainage, which further extends the box’s underground service life (typically 3-5 years).

Q2. What do you do with a ground wire in a PS-GT series plastic junction box?

Plastic junction boxes (like the PS-GT series) do not require grounding the box itself (unlike metal boxes), but the ground wire still needs proper handling to meet safety standards:

Secure the ground wire: Use the PS-GT’s built-in M4 copper nuts to fix a ground terminal block inside the box. Connect the ground wire (e.g., green or bare copper wire) to the terminal block—ensure a tight, low-resistance connection (avoid loose wires that cause arcing).

Compliance with standards: If the circuit includes a ground wire (common in outdoor power systems), bundle it with other wires in the box but do not connect it to the plastic shell. The PS-GT’s CE and IEC60439 certifications confirm this setup meets global electrical safety rules.

Practical note: For heavy-duty scenarios (e.g., 240V commercial wiring), use a dual-function terminal block that accommodates both power wires and the ground wire—this keeps the PS-GT’s interior organized and avoids wire tangles.

Q3. Can you splice wires together in a PS-GT series junction box in an attic?

Absolutely—the PS-GT series is ideal for attic wire splicing, as it addresses the attic’s unique challenges (temperature fluctuations, dust, and potential moisture):

Temperature resistance: The PS-GT’s ABS/PC material tolerates attic temperature ranges (-20℃ to +80℃), which prevents the box from becoming brittle in winter or deforming in summer (common with low-quality plastic boxes).

Dust & moisture protection: Attics often accumulate dust and may have occasional moisture (e.g., from roof leaks). The PS-GT’s IP65 rating and sealed lid block dust intrusion and splashed water, protecting the splice from corrosion or short circuits.

Size advantage: Even small PS-GT models (300×200×160mm) have enough space for splicing 4-6 wires (e.g., 14 AWG attic lighting wires). Use insulated wire nuts for the splice, then place them inside the box—avoid leaving bare conductors exposed.

Q4. How close can water lines be to a PS-GT series electrical junction box?

While there is no universal mandatory standard for the distance between water lines and electrical boxes, the PS-GT series’ design allows for a safe minimum distance of 30cm (12 inches)—with additional safeguards:

Protection from splashes: The PS-GT’s IP65 rating resists accidental water splashes (e.g., from leaking water lines), so a 30cm gap reduces the risk of direct water contact with the box. For areas with frequent water exposure (e.g., attic water heaters or outdoor hose bibs), increase the distance to 50cm.

Material compatibility: The PS-GT’s ABS/PC plastic is non-conductive and resistant to water damage—unlike wood or low-grade plastic that absorbs moisture. Even if water lines are nearby, the box’s sealed design prevents internal wiring from getting wet.

Installation advice: Mount the PS-GT box at least 15cm above the attic floor or outdoor ground (to avoid water pooling around the base). If water lines run parallel to the box, use a waterproof barrier (e.g., plastic sheeting) between them—this adds an extra layer of protection.
