GGD Fixed-Type Low Voltage Switchgear Cabinet - 400V / 415V, up to 3150A
GGD is the workhorse fixed-type low voltage switchboard: devices bolted onto a mounting plate behind a hinged door, fed from a top-mounted busbar system. Rated to 3150A with 50kA short-circuit withstand, verified to IEC 61439 and GB 7251. It is the highest-volume LV board across Middle East and African projects, and for most panel builders it is the first product they ever make.
WHY GGD STILL SELLS
Fixed construction has no drawer mechanism, no isolating contacts and no racking interlock, so there is far less to manufacture, far less to go wrong, and the price is substantially lower than a withdrawable board. For an incomer and feeder board that is switched rarely and can be shut down for maintenance, that is the correct engineering trade-off, not a compromise.
THE MARGIN PROBLEM, STATED HONESTLY
Because GGD is easy to build, everyone builds it. Panel builders across our markets report the same thing: severe product homogenisation, price competition down to sheet metal cost, and shrinking margins. If you are selling GGD today, your competitors are quoting the same board.
There are two ways out and we support both. Build a better GGD - verified design, correct busbar bracing, proper Form separation and real IEC 61439 evidence, so you win the tenders that actually check. Or move up to drawout with GCK, GCS or MNS, where fewer local builders can qualify. An Egyptian client who made that second move lifted profit by 40%.
WHAT WE SUPPLY
Complete cabinets, or a CKD kit for local assembly, or drawings plus components so your workshop builds under your own brand. The package includes GA drawings, BOM, wiring diagrams and QC checklists, the busbar support and insulation system, doors, locks, hinges and handles, and on-site or online assembly training.
DESIGN VERIFICATION IS THE SELLING POINT
IEC 61439 verifies the complete assembly - enclosure, busbar system, separation, temperature rise, short-circuit withstand and IP rating together. A cabinet fitted with certified breakers is not itself a verified assembly, and this is where cheap boards fail inspection. We supply the verification evidence for the assembly as built.
Configured to the destination voltage: 415V/240V for Qatar, Kuwait, Oman, Nigeria and Kenya; 400V/230V at 60Hz for Saudi Arabia; 400V/230V at 50Hz for UAE, Iraq, South Africa and Eastern Europe; 380V/220V for Russia and CIS; 525V for South African mining.
PRIMARY APPLICATIONS
- Main distribution board at the LV side of a distribution substation - the core application in every market we serve.
- Building main switchboards in commercial towers, hotels, hospitals, malls and airports.
- Industrial plant main and sub-distribution: cement, steel, textiles, food processing, packaging.
- Water treatment, desalination and pumping station distribution boards.
- Generator and standby power changeover boards.
- Housing scheme and residential development main boards on African and Middle East electrification projects.
- Solar PV plant auxiliary and LV collection distribution.
- Industrial estate and free-zone unit supplies.
TYPICAL BOARD FUNCTIONS
Incomer section with ACB, metering and protection; bus coupler for dual-transformer arrangements; outgoing feeder sections with MCCBs; capacitor bank compartment for power factor correction; metering and control section.
WHO BUYS THIS FROM US
Local panel builders and switchgear assemblers producing for their own domestic market, electrical distributors supplying contractors, and EPC contractors sourcing boards for a specific project. Most buy the component and drawing package rather than finished cabinets, because importing complete boards means paying freight on air.
REGIONAL FIT
- Middle East: 415V and 400V distribution. Saudi Arabia requires 400V 60Hz verification. High switchroom ambient of 50-55C demands temperature-rise verification above the IEC +40C reference. SASO SABER, DEWA, KAHRAMAA, MEW and Oman DCRP documentation supported.
- Africa: very high volume in building services, industrial and electrification projects. SONCAP applies - switchgear is regulated under HS 8536. KEBS PVoC for Kenya. Wide grid voltage swing makes protection coordination and under-voltage settings important.
- Russia and CIS: 380V/220V with genuine EAC certification under TR CU 004/2011 and TR CU 020/2011.
- Eastern Europe: 400V, CE marked under LVD and EMC to EN 61439.
NOT SUITABLE FOR
Installations where a feeder must be replaced without shutting the board - specify GCS or GCK. Motor-dominated plant needing many starters - specify GCK. Projects where the client mandates withdrawable or internationally standardised construction - specify MNS.

WE SELL THE CAPABILITY, NOT JUST THE BOX
Most suppliers quote you a finished cabinet. We would rather make you the factory. Over 15 years we have equipped more than 300 partner enterprises in 72 countries to build their own low voltage switchgear locally, using our drawings, our components and our training. If you only want finished cabinets we will supply those too - but read what the alternative saves first.
1. TECHNICAL PACKAGE - GA DRAWINGS AND ENGINEERING
Complete general arrangement drawings, busbar layouts, single-line and schematic diagrams, drilling and cut-out templates, torque tables, BOM with part numbers, and assembly instructions. Drawings are issued in DWG and PDF, dimensioned in millimetres, and revised free of charge for your project variations. Your engineer works from a design that has already been verified, instead of reverse-engineering a competitor's board.
2. COMPONENT SUPPLY - CKD KIT FROM 2,000+ SELF-DEVELOPED PARTS
We manufacture over 2,000 of our own switchgear components and 38+ patents sit behind them. That matters because the parts that decide whether a cabinet passes inspection - busbar supports, insulators, drawer isolating contacts, racking mechanisms, interlocks - are not reliably available on the open market at consistent quality. You buy the kit flat-packed, add local sheet metal and labour, and the freight bill collapses. A South African distributor cut total cost by 40% doing exactly this; logistics alone had been eating 25% of their landed cost.
3. LEAD TIME
Building locally from a kit removes the ocean freight leg from your delivery promise. The same South African partner went from a 3-month lead time to 5 weeks. In markets where the contractor pays liquidated damages for late energisation, that is often worth more than the price difference.
4. TRAINING AND ASSEMBLY SUPPORT
On-site or online training for your assembly team: frame build, busbar bracing and torquing, drawer alignment, Form separation, wiring discipline, routine testing. We also run remote support during your first production batches. An Indonesian client used this route to enter the high-end panel market within 4 months and lifted margin by 35%.
5. OEM AND ODM - YOUR BRAND ON THE DOOR
Nameplate, colour, layout, packaging and documentation to your brand. Non-disclosure agreements and territory protection for distributors who are developing a market. You sell as a manufacturer, not as a re-seller.
6. CERTIFICATION AND SUBMITTAL SUPPORT
Design verification evidence to IEC 61439-1 and IEC 61439-2, type-test reports, material certificates and QC records for your tender submittals. Country routes supported: EAC under TR CU 004/2011 and TR CU 020/2011 for the EAEU, CE under LVD 2014/35/EU and EMC 2014/30/EU to EN 61439 for the EU, SASO SABER PCoC plus per-shipment SCoC for Saudi Arabia, SONCAP for Nigeria under HS 8536, KEBS PVoC Routes A/B/C for Kenya, and utility submittals for DEWA, KAHRAMAA, MEW, Oman DCRP and ICIGI.
7. AFTER-SALES AND SPARES
Technical response within 24 hours. Spare parts kept to the same drawing revision for the life of the design, so a drawer bought in year one still fits a cabinet built in year five. Warranty 12 months from commissioning or 18 months from shipment.
8. COMMERCIAL TERMS
FOB, CFR, CIF, DDP and Ex-Works. Consolidated container loading with mixed products. Trade Assurance, T/T and L/C at sight. Sample and pilot batch orders accepted before you commit to volume.
QUALITY CONTROL - VERIFIED ASSEMBLY, NOT A FOLDER OF COMPONENT CERTIFICATES
The most common reason a low voltage board is rejected on site is not a faulty breaker. It is that the assembly itself was never verified. IEC 61439 verifies the complete assembly - enclosure, busbar system, internal separation, temperature rise, short-circuit withstand and IP rating, together. A cabinet fitted with certified devices is not automatically a verified assembly, and inspectors in our markets increasingly know the difference.
DESIGN VERIFICATION - IEC 61439-1 AND -2
Strength of materials and parts, degree of protection, clearance and creepage distances, protection against electric shock and integrity of the protective circuit, incorporation of switching devices and components, internal electrical circuits and connections, terminals for external conductors, dielectric properties, temperature-rise limits, short-circuit withstand strength, and electromagnetic compatibility. Verification evidence is issued for the assembly as built and supplied for your tender submittal.
ROUTINE VERIFICATION - EVERY CABINET, BEFORE IT SHIPS
1. Enclosure inspection - dimensions, squareness, door alignment and gap, panel flatness, weld and bolt integrity.
2. Coating - pre-treatment, powder coat thickness measured, adhesion cross-hatch test, RAL colour verification, salt spray on batch samples.
3. Busbar system - phase sequence and colour identification, bar section and spacing against drawing, insulator and holder installation, every joint torqued to specification and marked.
4. Protective circuit continuity - PE bar and door bonding tested at the specified test current, resistance recorded.
5. Wiring - against the schematic, terminal tightness, ferrule and labelling check, bending radius and segregation of power and control.
6. Dielectric test - power-frequency withstand for one minute at the rated test voltage, insulation resistance measured and recorded.
7. Functional test - protection, interlocks, indication, metering, control logic and, where fitted, communication.
8. Degree of protection - gasket continuity, cable gland plates, door seal compression; IP verification per the stated rating.
9. Final inspection - nameplate data, circuit labelling, drawing pack, spare parts, tidiness, packing.
WHAT YOU RECEIVE
Routine test certificate, design verification evidence, inspection checklist with the tester's mark, material and coating certificates, device certificates, GA and schematic drawings as-built, and the operation and maintenance manual.
INDEPENDENT AND WITNESSED TESTING
Witnessed factory acceptance testing available for EPC and utility projects; this is a standard requirement on Saudi SEC work. Third-party inspection by SGS, BV, TUV or Intertek accepted and coordinated at the buyer's request. Pre-shipment inspection reports with photographs are issued for every order.
MANAGEMENT SYSTEM
ISO 9001 quality management. Incoming material inspection with certificate traceability, in-process inspection at frame, busbar and wiring stages, and final inspection before packing. Non-conformances are recorded, root-caused and closed - a discipline that matters more than any single certificate.
