Different Specifications and Variants of NEMA Socket JL-240 and How to Choose

NEMA sockets (National Electrical Manufacturers Association sockets) are standardized connectors used for various electrical equipment. The JL-240 series sockets are primarily used in outdoor lighting systems, especially street lighting. This series has different specifications and variants to meet diverse application requirements. Below is a detailed description and selection guide.

Detailed description:

1. Low Voltage Contact Arrangement

Type A: Four low voltage contacts (4 pads)

Type B: Two low voltage contacts (2 pads)

2. Wire Gauge and Grade

16 (or 16G): AWG #16, AWM1015 (or AWG #16, AWM3321)

14 (or 14G): AWG #14, AWM1015 (or AWG #14, AWM3321)

3. Wire Length

Standard length: 6 inches or customized as required.

4. Rear Cover Protection Level

Type R: Includes rear cover for IP65 protection (with equal or higher IP protection)

Type S: Sealed rear cover for IP66 protection (with equal or higher IP protection)

5. Mounting Bracket Thickness

Type L2: Aluminum 1.8~2.0mm thick

Type L3: Aluminum 2.8~3.0mm thick

Selection Guide for NEMA Socket JL-240

1. Choosing Based on Application Environment

Outdoor Environments: Select models with high protection levels (such as IP65 or IP66) to ensure normal operation in harsh weather conditions.

Industrial Environments: Choose models with corrosion-resistant and high-strength brackets (such as aluminum 2.8~3.0mm thick) for increased durability.

2. Choosing Based on Load Type

High-Power Equipment: Select models with larger wire gauge (such as AWG #14) and longer wire lengths to ensure the safety and stability of current transmission.

Standard Power Equipment: Select models with standard wire gauge (such as AWG #16) and standard wire lengths to meet general lighting needs.

3. Choosing Based on Installation Requirements

Rotation Limitation Function: Choose models with limiting features to ensure the socket does not rotate easily after installation, maintaining a stable connection.

Low Voltage Signal Connection: Select Type A or Type B low voltage contact arrangements as needed to ensure accurate and reliable signal connections.
