Powering Events: Key Connectors You Need To Know

Ever found yourself staring at a tangle of cables backstage, wondering which plug goes where? In the UK events industry, understanding power connectors is crucial for both safety and efficiency. From small gigs to massive festivals, the right connections are essential for keeping the show running smoothly. This guide will demystify the various cables and connectors you’ll encounter, from standard 13A plugs to complex Socapex systems. Misunderstanding or misusing power connections can lead to equipment damage, electrical hazards, and even serious injury, so let’s get it right.

Domestic Power (13A):

The familiar 13A plug (BS 1363) is the backbone of domestic electrical supply in the UK.

• Description: The standard three-pin plug found in homes and offices.
• Use Cases: Ideal for small events, powering laptops, small audio setups, and basic lighting.
• Limitations: Limited power capacity, not suitable for high-demand equipment.

15A Round Pin Connector:

• Description: A round pin connector, often found in older installations or specific lighting setups.
• Use Cases: Historically used for stage lighting, and sometimes still found in older theatrical installations.
• Dimmer Circuits: Often, these 15A round pin connectors are connected to dimmer circuits.

• Warning: Always verify if a 15A round pin connector is on a dimmer circuit before plugging in any equipment. If you are unsure, consult a qualified electrician.

Industrial Single-Phase Connectors (16A, 32A, 63A):

For higher power needs, industrial IEC 60309 connectors come into play.

• Description: Round, robust connectors designed for industrial use. While often seen in blue (230V) or yellow (110V), many single-phase connectors, especially those used in professional event settings, are black. Black connectors still adhere to the IEC 60309 standard.
• IP Rating: Most of these connectors have an IP44 or IP67 rating, indicating protection against solid objects and splashes of water (IP44), or against dust and temporary immersion (IP67). 

16A (Blue):

• Use Cases: Small PA systems, basic lighting rigs, small power tools.

32A (Blue):

• Use Cases: Larger lighting rigs, medium-sized PA systems, catering equipment.

63A (Blue):

• Use Cases: Large events, powering substantial lighting and audio setups.

110V (Yellow):

• Used for increased safety, often on construction sites, and sometimes in events for specific equipment such as Cherry Pickers & Scissor Lifts. A transformer would be needed to connect these to your main power supply

Three-Phase Connectors (16A, 32A, 63A, 125A):

For high-power applications, three-phase power is essential.

• Description: Red IEC 60309 connectors designed for three-phase power.
• Explanation: Three-phase power delivers three alternating currents, providing a smoother and more efficient power supply for high-demand equipment.   
• Use Cases: Large-scale events, powering large audio systems, stage lighting, and industrial equipment.
• Amperage differences: Larger amperage connectors are physically larger, and designed to carry more current.

IEC Connectors (C13/C14, C19/C20):

Found in IT and audio equipment, IEC connectors are standardized for various devices.

C13/C14:

• Use Cases: Connecting computers, monitors, and other IT equipment.

C19/C20:

• Use Cases: High-power IT equipment, servers, projectors and some power distribution units.

PowerCON and True1:

Locking connectors for professional audio and lighting.

PowerCON (Blue/Grey):

• Description: Locking connectors for secure power connections. Blue is typically power in, grey is power out.
• Use cases: Stage lighting, audio equipment, and other event gear.
• Explanation: The locking mechanism prevents accidental disconnection.

PowerCON TRUE1:

• Description: Weatherproof and lockable connectors, designed for outdoor and demanding environments.
• Advantages: IP65 rating, breaking capacity, and robust design.

Socapex (19-Pin):

For complex stage lighting setups.

• Description: Multi-pin connector used for stage lighting, allowing multiple circuits to be run through a single cable.
• Use Cases: Large-scale stage lighting rigs, simplifying cable management.
• Explanation: A single Socapex cable can carry multiple lighting circuits, reducing cable clutter. This cable is often used with a “break out” cable to many individual lighting fixtures.   

Safety Considerations:

Cable Lengths: Long cable runs can cause voltage drop, leading to equipment malfunction. Use cables of appropriate lengths, and consider using thicker cables or up rating cables for longer runs.
Qualified Electricians: Always use qualified electricians for installing and working with high-power electrical systems. If unsure ask!
Cable Ratings: Ensure cables are rated for the current they will carry.
RCD Protection: Use residual current devices (RCDs) to prevent electrical shocks.
Cable Management: Keep cables tidy to prevent tripping hazards and damage. Use Cable ramps where necessary

PAT Testing: Regularly test electrical equipment for safety. For your peace of mind, all our equipment is thoroughly tested before use to ensure the highest safety standards. We also offer PAT testing Services
Weather Conditions: Use weatherproof cables and connectors for outdoor events.
Circuit Verification: Always verify circuits, especially before plugging into 15A round pin sockets, to avoid damage to equipment.
