How Many Circuits Does a Standard 19-Pin Socapex Contain?
1. Introduction
19-pin Socapex is widely used in portable stage lighting power distribution systems. The introduction of these cables has made stage wiring and power distribution simpler, faster, and safer.
Some users may ask:
How Many Circuits Does a Standard 19-Pin Socapex Contain?
Typically, a standard Socapex cable has 6 circuits.
This is determined by the structure of the 19-pin Socapex connector.
Connector Pin Functions
| Function | Number of Pins |
|---|---|
| Line conductors | 6 |
| Neutral conductors | 6 |
| Ground conductors | 6 |
| Spare pin | 1 |
| Total | 19 |
This article will briefly introduce Socapex and explain why there are 6 circuits.
2. 19-Pin Socapex Wiring Diagram
The most intuitive way to explain why there are 6 circuits is to show the wiring diagram of the Socapex connector.
Socapex Break (Fan) In/Out Cable Wiring Diagram
The photo below shows the manufacturing process for a Socapex breakout (fan-out) cable. I have already connected two 3×2.5 mm² wires.
Each circuit corresponds to one 3×2.5 mm² wire. One 3×2.5 mm² wire occupies 3 pins. Since 19 = 3 × 6 + 1, it is clear that there are a maximum of 6 circuits.
Key Point: Each circuit requires three pins (Line, Neutral, and Ground), which is why a 19-pin Socapex connector can accommodate a maximum of six circuits plus one spare pin.
Socapex Extension Cable Wiring Diagram
This differs from the Break In/Out cable wiring diagram. There are three different wiring methods for Socapex extension cables. The line and neutral pins must always be connected. The main difference lies in how the ground wires are connected.
We can use 19-core, 14-core, or 13-core cables to complete the wiring.
19-core: Each pin is connected to a separate conductor. One ground conductor per circuit.
This wiring method is the safest and is suitable for high-load situations.
14-core: Six groups of circuits share a single ground conductor. Additionally, there is one spare wire.
13-core: Six circuit groups share a single ground conductor. There is no additional spare conductor.
The figure below illustrates the wiring methods for 14-core and 13-core cables that share a ground wire.
Comparison of Different Socapex Cable Constructions
| Cable Type | Ground Arrangement | Weight | Cost | Recommended Load |
|---|---|---|---|---|
| 19-core | Dedicated | High | High | Heavy duty |
| 14-core | Shared | Low | Low | Standard touring |
| 13-core | Shared | Low | Low | Light duty |
4. 19-Core vs 14-Core Socapex: Which Should You Choose?
14-core and 13-core cables clearly pose risks when used under high-load conditions. However, these two cable types use less copper, which means they are less expensive and lighter in weight, so they are still widely accepted.
For example:
- A 19×2.5mm² cable that is 30 meters long weighs 32 kg, which may be too heavy for a single person to carry.
- A 14×2.5mm² Socapex cable of the same length weighs 16 kg, making it much easier to transport and install.
5. Common Mistakes When Selecting Socapex Cables
Failing to Consider the Number of Conductors in Socapex Extension Cords
In certain high-load situations, 13- or 14-conductor cables cannot replace 19-conductor cables, which poses significant safety hazards.
Selecting the Wrong Cable Size
Socapex cables are available in 2.5mm²/12 AWG. The maximum current carrying capacity for 2.5 mm² is 20 amps, while for 12 AWG it is 25 amps.
Forget to Add Your Own Logo and Length Markings to Heat-Shrink Tubing
For some stage equipment rental service providers, customizing heat-shrink tubing can help prevent equipment theft during the rental period.
During stage installation, this prevents cables from becoming indistinguishable due to excessive and tangled wire ends.
5. FAQ
Are all Socapex cables 19-core?
No. There are also 14-core, 13-core, and other configurations. Ask the supplier before ordering.
Can Socapex cables carry more than 6 circuits?
No. The maximum is 6 circuits.
Are 19-conductor Socapex cables safer than 14-conductor ones?
Yes. Each circuit in a 19-conductor Socapex cable has its own dedicated ground wire, whereas the 14-conductor version shares a single ground wire.
What cable sizes are typically used in the Socapex system?
2.5 mm² (20 amps) and 12 AWG (25 amps).
What types of sheath are typically used for Socapex cables?
Depending on your application needs, you can choose between highly flexible PVC or rubber jackets.
