Question 1

Which cable should I use for power distributors?

Accepted Answer

For professional event and stage applications, use H07RN-F rubber cables for general outdoor use and touring applications. Choose the cross-section based on load: 1.5 mm² for up to 16A (3.6 kW), 2.5 mm² for up to 25A (5.75 kW), 4 mm² for up to 32A (7.4 kW), and 6 mm² or larger for high-power applications exceeding 32A. For extreme cold conditions or high-abrasion environments, consider H07BQ-F or PUR-jacketed cables. Always ensure cables are rated for the voltage and current of your application, and calculate voltage drop for long cable runs to determine if a larger cross-section is needed.

Question 2

What types of power distributors are available for events?

Accepted Answer

Power distributors for events range from simple rubber hanging distributors with three to six Schuko outputs (suitable for basic lighting and small equipment) to professional touring distribution boxes with multiple CEE 16A, 32A or 63A outputs, integrated circuit breakers and RCD protection. Weatherproof distributors with IP65 or IP67 ratings are essential for outdoor festivals and exposed installations. High-end touring systems feature metering displays, remote monitoring capabilities, and quick-lock housings for rapid setup. Choose the distributor type based on your power requirements, number of devices, environmental conditions and the level of circuit protection needed.

Question 3

What are the three main types of cable connectors used in stage technology?

Accepted Answer

The three main connector types in professional stage and event technology are Schuko plugs (standard 230V household connectors rated up to 16A, used for general equipment), CEE connectors (industrial plugs available in 16A, 32A and 63A ratings for single-phase and three-phase power, colour-coded by voltage), and specialised high-current systems such as Powerlock, True1 or Camlock connectors (used in touring applications for currents exceeding 63A). Each type is designed for specific voltage, amperage and environmental conditions, with IP ratings indicating protection against dust and water. Always match the connector type to your power requirements and installation environment.

Question 4

What is a distributor socket and how is it used?

Accepted Answer

A distributor socket (also called a distribution box or power splitter) is a device that allows you to split a single power source into multiple outputs, enabling several devices to be powered from one connection. In event technology, distributor sockets range from basic rubber units with three to six Schuko outlets to sophisticated touring distribution systems with multiple CEE outputs, integrated circuit breakers and residual current devices. They are used to power lighting fixtures, sound equipment and other stage technology from a central power supply, with professional models featuring weatherproof housings rated IP44 or higher for outdoor use and quick-lock systems for rapid deployment.

Question 5

What IP rating do I need for outdoor event power distribution?

Accepted Answer

For outdoor events, use power distribution equipment with a minimum IP rating of IP44, which provides basic splash protection suitable for covered stages. For exposed outdoor installations such as festival stages or ground-level distribution points, IP65 is recommended — this rating ensures dust-tight protection and resistance to water jets from any direction. For equipment that may be exposed to temporary immersion (such as ground-level boxes in areas prone to flooding), IP67-rated connectors and distributors are essential. Remember that IP ratings apply only when connectors are properly mated and protective covers are closed, so always ensure connections are secure and covers are in place during operation.

Question 6

How do I calculate the correct cable cross-section for my event?

Accepted Answer

To calculate the correct cable cross-section, first determine the total load in amperes that the cable must carry. As a general guide, 1.5 mm² cable handles up to 16A (3.6 kW at 230V), 2.5 mm² handles up to 25A (5.75 kW), 4 mm² handles up to 32A (7.4 kW), and 6 mm² or larger is required for loads exceeding 32A. For long cable runs, calculate voltage drop using the formula: voltage drop (V) = 2 × length (m) × current (A) × resistance per metre (Ω/m). Voltage drop should not exceed 3% for lighting circuits (approximately 7V at 230V) or 5% for power circuits (approximately 11.5V). If voltage drop is excessive, increase the cable cross-section.

Question 7

What is the difference between single-phase and three-phase power distribution?

Accepted Answer

Single-phase power distribution uses one live conductor (phase), one neutral and one protective earth, typically delivered via a Schuko plug or CEE single-phase connector, providing 230V and up to 16A or 32A depending on the connector rating. Three-phase power distribution uses three live conductors (L1, L2, L3), one neutral and one protective earth, typically delivered via a five-pin CEE connector, providing 230V between each phase and neutral, and 400V between phases. Three-phase systems allow much higher total power delivery — a 32A three-phase supply can provide up to 22 kW compared to approximately 7.4 kW for a 32A single-phase supply. Three-phase distribution is essential for professional stage and event applications with high power requirements.

Question 8

Which cables and distributors should I buy for touring productions?

Accepted Answer

For touring productions, invest in heavy-duty H07RN-F rubber cables with cross-sections of 2.5 mm² or larger, premium connectors from manufacturers such as Neutrik, PCE or Mennekes, and professional touring distribution boxes with IP65 or higher ratings, integrated circuit protection and quick-lock housings. Choose cables with reinforced strain relief and clear specification marking, and ensure all connectors have impact-resistant housings and reliable cable grips. Budget €150–€400 for basic 6-way Schuko distributors with RCD protection, €400–€800 for CEE 32A touring distributors, and €1,200–€3,000 or more for high-current 63A systems. The additional cost of touring-grade equipment is recovered through reduced failures, lower maintenance and longer service life under the rigours of constant transport and setup.
