Low current systems are the backbone of every modern building in Saudi Arabia, from hospitals and hotels to government complexes and industrial facilities. Properly designed ELV systems ensure the safety, security, communication, and automation of every space they serve. Whether you are planning a new build or upgrading an existing installation, choosing the right supplier makes all the difference. In this complete 2026 guide, El Buroj covers everything you need to know: system types, sector applications, and Saudi standards.
What are low current systems?
Low current systems, also known as Extra Low Voltage (ELV) systems, are electrical systems that operate at voltages below 50V AC or 120V DC. Unlike standard power systems, ELV systems are dedicated to data transmission, communication, security, life safety, and automation rather than supplying power to equipment directly. They form an integrated infrastructure layer inside every building, running in parallel with the main electrical power system.
ELV vs LV vs HV: Technical Comparison
Understanding where low current systems sit within the broader electrical classification is essential for correct design and compliance:
ELV (Extra Low Voltage):
Operates below 50V AC / 120V DC and is commonly used in CCTV systems, access control, fire alarm systems, public address (PA), and data networks.
LV (Low Voltage):
Covers the range between 50V – 1,000V AC and is mainly used for building power distribution, lighting systems, and HVAC applications.
HV (High Voltage):
Refers to systems operating above 1,000V AC, typically used in substations, power transmission networks, and industrial high-voltage feeders.
ELV systems, the category that covers all ELV systems, require separate conduit runs, dedicated earthing, and specialist design to avoid electromagnetic interference with LV power circuits.
Proper grounding is critical for the safety and performance of ELV infrastructure. Learn more about the different types of earthing systems used in Saudi electrical installations.
Why Low Current Systems Are Essential in Modern Buildings
ELV systems are no longer optional in modern Saudi construction projects. They are mandated by the Saudi Building Code (SBC), civil defense regulations, and SEC standards for all commercial, healthcare, and institutional buildings. Beyond compliance, well-integrated extra low voltage systems directly improve occupant safety, operational efficiency, energy management, and building asset value.

FAQ
What are low current systems?
Low current systems are Extra Low Voltage (ELV) building systems operating below 50V AC, covering security, fire alarm, communication, automation, and life safety. They run in parallel with the main power system and are required in all modern commercial and institutional buildings in Saudi Arabia.
What is the difference between low current systems and power systems?
Power (LV) systems supply electricity to equipment and lighting at 220–380V. Extra-low voltage systems transmit data, signals, and control commands at voltages below 50V. Both share the same building infrastructure but must be installed in separate conduits to prevent interference.
Are low current systems mandatory in Saudi Arabia?
Yes. The Saudi Building Code (SBC), Civil Defense regulations, and SEC requirements mandate specific extra-low voltage systems, including fire alarms, emergency lighting, and structured cabling for all commercial, healthcare, and institutional buildings above a certain size or occupancy level.
How long does a low current project installation take?
The timeline depends on building size and system complexity. A standard office floor takes 2-4 weeks. A full hospital or mall project typically requires 3-9 months, including testing, commissioning, and authority approvals.
Can El Buroj supply and install ELV systems for hospitals?
Yes. El Buroj provides complete ELV packages for hospitals, including nurse call, fire alarm, CCTV, structured cabling, PA/PAVA, and BMS, all compliant with MOH guidelines and CBAHI accreditation requirements.
