What Voltage and Electrical Standards Apply to Lighting and Appliances from China?

China’s domestic supply is 220 V at 50 Hz, so anything a Chinese factory builds for its home market is wrong for a US project and only accidentally right for a UK, EU, Australian or Gulf one. What you must specify is the destination’s supply: 120 V / 60 Hz in the United States and Canada, with commercial lighting frequently run at 277 V; 230 V / 50 Hz in the UK, the EU, Australia and New Zealand; 220–240 V / 50 Hz across the Gulf. Voltage alone is not enough. Every luminaire, socket, switch and appliance also needs the destination’s safety approval — an NRTL listing for the US, CE with a UK or EU Declaration of Conformity, the RCM for Australia, SASO through SABER for Saudi Arabia — and the dimming protocol has to match the control system, which is where most commissioning failures actually occur. This guide sets out what to write into the specification, market by market. As your China sourcing partner, FBM Sourcing manages this end-to-end.

What Voltage, Frequency and Plug Does Each Market Use?

• United States and Canada: 120 V, 60 Hz for general power, with NEMA 5-15 receptacles. Commercial buildings commonly distribute 480/277 V three-phase, so lighting circuits run at 277 V while receptacles stay at 120 V; 208 V appears on larger single-phase loads. Specifying a 120 V-only luminaire for a 277 V lighting circuit is a rework item, not a variation.
• United Kingdom: 230 V, 50 Hz, BS 1363 13 A fused plug and socket. Lighting circuits are 230 V.
• European Union: 230 V, 50 Hz, CEE 7 Schuko or French-pattern sockets depending on country.
• Australia and New Zealand: 230 V, 50 Hz, AS/NZS 3112 flat-pin plug.
• Gulf states: 220–240 V, 50 Hz. The UK BS 1363 pattern is dominant in the UAE, Saudi Arabia and Qatar; Saudi Arabia has been standardising on 230 V.
• Japan: 100 V, split between 50 Hz in the east and 60 Hz in the west — the one market where frequency varies inside the country.

Frequency is the part buyers underestimate. Electronic LED drivers are usually built with a universal input of 100–277 V, 50/60 Hz, so an LED luminaire can often be made market-agnostic at the driver. Anything with a motor or a magnetic component is not: extract fans, pumps, compressors, transformers and time switches run slower and hotter at 50 Hz than at 60 Hz, and a 60 Hz-rated fan on a 50 Hz supply loses roughly a sixth of its speed. Specify the frequency for every motorised item, including the motorised shading and the minibar compressor.

Which Safety Approval Does the Destination Require?

A universal-input driver does not carry a universal approval. Market access is a separate legal test from electrical compatibility, and it is the one that stops a container at the border or an installation at inspection.

• United States: listing by a Nationally Recognized Testing Laboratory, shown by a cULus, ETL or CSA mark applied to the product. Luminaires are tested to UL 1598, LED equipment to UL 8750, and emergency lighting to UL 924. Electronics must also satisfy FCC Part 15 for emissions. Local inspectors reject unlisted equipment regardless of what test report accompanies it.
• Canada: CSA C22.2 series, shown by a cCSAus or cULus mark covering both markets.
• United Kingdom: UKCA marking with a UK Declaration of Conformity against the designated standards, typically the BS EN 60598 series for luminaires. See our comparison of UKCA and CE marking for Chinese products on UK projects.
• European Union: CE marking under the Low Voltage Directive 2014/35/EU, the EMC Directive 2014/30/EU and RoHS 2011/65/EU, plus Ecodesign and energy labelling under Regulations (EU) 2019/2020 and 2019/2015 for light sources.
• Australia and New Zealand: the Regulatory Compliance Mark, with in-scope equipment registered in the national database under the Electrical Equipment Safety System and tested to the AS/NZS 60598 series. Our detailed note on SAA certification and the RCM for lighting and electrical products covers the registration route.
• Saudi Arabia: SASO conformity through the SABER platform — a Product Certificate of Conformity for the model, then a Shipment Certificate of Conformity for each consignment. Without the shipment certificate the goods do not clear.
• United Arab Emirates: conformity under the ECAS and Emirates Quality Mark schemes, described in our note on UAE conformity requirements for building materials from China.

One route saves real time on multi-market packages: the IECEE CB Scheme. A CB test report and certificate issued by a recognised testing laboratory against the IEC standard can be converted into national certification by member bodies, subject to declared national differences. A factory that already holds a CB certificate for a luminaire family can usually reach UKCA, CE and RCM far faster than one starting from a Chinese domestic GB report.

Why Do Dimming and Controls Cause Most of the Failures?

Voltage errors are caught at the factory. Dimming errors are caught on site, at commissioning, after everything is installed — which makes them far more expensive. The control protocol is a specification line in its own right and must be stated for every dimmable fitting.

• Phase dimming — leading-edge TRIAC or trailing-edge ELV — is common in US residential and light commercial work, and requires a driver explicitly listed as compatible with the named dimmer model.
• 0–10 V analogue is the default for US commercial lighting, using two extra low-voltage control conductors.
• DALI and DALI-2 dominate commercial and hospitality projects in the EU, UK and Australia, and give addressable control and status feedback.
• Wireless systems — Zigbee, Bluetooth mesh, Casambi — must match the building’s chosen ecosystem; drivers are not interchangeable between them.

Ask the factory for the driver manufacturer, model number and published dimmer compatibility list, not for the word “dimmable”. On a hotel package, a mismatch between a room-control system and a bedside luminaire driver is discovered at mock-up room stage if you are lucky and at practical completion if you are not.

What Else Changes With the Destination Market?

Beyond volts, hertz and the approval mark, five specification lines move with the country and are worth writing out explicitly.

• Protection class and earthing. Class I fittings need a protective earth conductor and a three-core supply; Class II are double-insulated and take two cores. US practice grounds through the fixture housing with wire-nut terminations and fixture wire; UK, EU and Australian practice uses terminal blocks and a separate earth core. Mixing conventions produces a fitting an electrician cannot legally terminate.
• Ingress and impact protection. IP44 for bathroom zones, IP65 for external and wash-down areas, IP66/IP67 for landscape and in-ground fittings; IK08 or above where vandal resistance is called for in corridors, car parks and school circulation.
• Emergency lighting duration. Non-domestic premises in the UK generally require three hours of emergency duration under BS 5266-1, while the US requires a minimum of 90 minutes under NFPA 101, with UL 924 listing for the equipment. Same building type, different battery.
• Energy compliance. California Title 24 imposes efficacy and JA8 requirements on much interior lighting; the EU applies Ecodesign minimum efficacy; Australia applies MEPS to in-scope products. See our note on California Title 24 for lighting and glazing from China.
• Wiring accessories and appliances. Sockets and switches follow UL 498 and NEMA patterns in the US, BS 1363 and BS EN 60669 in the UK, AS/NZS 3112 and AS/NZS 3133 in Australia. Guest-room appliances — kettles, hairdryers, minibars, safes — each need the destination approval, and a 2 kW kettle on a 120 V supply draws roughly 17 A against about 9 A at 230 V, which changes the circuit design as well as the product.

What Should the Specification and Purchase Order Say?

Nine fields, per line item, remove almost every electrical dispute we have seen on a project package:

• Supply voltage and frequency, written as a number, not as “standard”.
• Approval scheme and mark required — cULus, UKCA, CE, RCM with EESS registration, SASO via SABER — and the requirement that the mark be applied to the product, not to the carton.
• Applicable product standard and edition, for example UL 1598, BS EN 60598-1, AS/NZS 60598.1.
• Driver make, model and dimming protocol, plus the dimmer or control system it must work with.
• Protection class, IP rating and IK rating.
• Plug type, cable length and colour code, or a stated flying-lead termination.
• Emergency duration and the standard it is tested to, where applicable.
• Energy-compliance requirement where the destination imposes one.
• Labelling and marking language, and the documents to be supplied — test report, Declaration of Conformity, certificate number.

Then verify the evidence rather than the assurance. A certificate should be traceable to an accredited laboratory and to the exact model, and the mark should be on a sample before mass production begins — our comparison of factory test reports and accredited laboratory testing explains why the distinction matters, and the resulting documents belong in the fire and life-safety handover pack.

Electrical requirements also vary across the Gulf states, and in some of them the plug pattern and voltage range are written into the national scheme rather than left to specification: see conformity rules in Qatar, Kuwait, Oman and Bahrain.

How FBM Sourcing Handles Electrical Specification on a Project Package

FBM Sourcing manages the entire China procurement package for overseas construction projects. On a hotel, apartment, school, office or healthcare package the lighting and electrical lines are set out at quotation stage with the destination voltage, frequency, approval scheme, product standard, driver and control protocol written against each item, because these are the fields Chinese factories default to their domestic values if nobody states them. We shortlist plants that already hold current certification for the destination market — an existing NRTL listing, UKCA and CE files, RCM registration or a CB certificate that can be converted — rather than plants promising to certify after the order, and we raise mismatches such as a 120 V-only fitting on a 277 V lighting circuit, or a driver with no compatibility listing for the specified dimmer, while the product can still be changed. A powered sample is checked against the specified control gear before mass production. Before shipment our own FBM Sourcing QC team inspects the goods at the factory — marks and rating plates, driver model against the approved sample, cable and termination type, IP sealing, labelling — with photo and video records delivered in stages. All quotations, invoices and shipping documents are issued by FBM Sourcing — you deal with us, and we carry the responsibility. For suppliers you nominate, we charge a 5% commission; for products we source for you, we quote a direct price. Sometimes, on a large project, the lighting alone fills full containers; sometimes the lighting shares containers with the other product categories of the same project; and sometimes, in one batch, we combine a dozen or more product categories from several projects of the same client into a few containers — always full containers, and for us this is routine, well-practised work.

If you are specifying lighting, wiring accessories or guest-room appliances for a commercial project, send us the lighting schedule, the control system, the destination port and the required-on-site dates. Our team will review it line by line and set out a quotation — use the quote button above or WhatsApp +86 135 6007 5057.
