ABB Inora 2 Gang 1 Way 20AX Switch Starry Black BL114-885

Two gang means the switch has two independently operated rockers for two separate circuits. One way means each circuit is controlled from one switch location rather than from two locations. The 20AX marking indicates a 20 A switch rating with additional suitability for certain lighting loads that produce high inrush currents. The connected load must still comply with the switch data sheet, cable rating, protective device and project design.

Yes. Each rocker can control a separate compatible lighting circuit, such as a ceiling light and decorative lighting, or two different lighting zones in the same room. The circuits must be correctly identified and wired, and their combined arrangement must follow the approved electrical design. This is a one-way switch, so each connected circuit is normally controlled only from this location.

The ABB Inora BL114-885 can be considered for UAE residential and commercial projects when its voltage, frequency, terminal capacity, mounting arrangement and certification match the project specification. UAE supplies are commonly 230 V at 50 Hz for single-phase applications. Final selection and installation should comply with the relevant local authority requirements, approved project drawings and applicable wiring regulations.

It may be used to switch compatible LED lighting circuits, provided the total steady-state load and driver inrush current remain within ABB's specified limits. LED drivers can generate a brief starting current significantly higher than their normal operating current, so suitability should not be assessed only by adding lamp wattages. For large LED groups, an electrician or engineer should verify the switching capacity and use a contactor or relay where required.

Installation should be completed by a qualified electrician. The supply must first be isolated, locked out where applicable and tested to confirm it is dead. The incoming live conductor and the two switched-live conductors are then connected to the terminals identified in ABB's wiring instructions. After confirming conductor size, terminal tightness, earthing continuity and box fit, the switch can be secured, aligned and tested. Always follow the terminal markings and installation sheet supplied with the product.

A conventional mechanical one-way switch generally interrupts the live conductor and does not normally require a neutral connection at the switch itself. However, the actual circuit arrangement must be confirmed from the ABB terminal markings and the project's wiring diagram. Neutral and protective-earth conductors must never be connected to a terminal unless it is specifically intended and identified for that purpose.

Use a compatible concealed or surface-mount wall box that matches the switch dimensions, fixing centres and installation method specified by ABB. The box should provide adequate depth for the terminals and conductors without sharp bends, compression or damaged insulation. Before procurement for a UAE construction project, confirm compatibility with the selected back box, conduit system, wall finish and other ABB Inora wiring accessories.

No, not as a standard two-way switching device. The BL114-885 is described as a one-way switch, intended to control each circuit from one location. Staircases, corridors and rooms requiring control from two locations normally need compatible two-way switches. For control from three or more locations, intermediate switching or an appropriate control system may also be required.

Do not assume that the decorative Starry Black finish makes the switch weatherproof. Outdoor, balcony, garden and wet-area installations require an enclosure and accessory with an appropriate verified IP rating for dust, moisture and local environmental exposure. Unless ABB documentation confirms the required protection level, install this switch only in a suitable dry indoor location or inside an approved weatherproof enclosure.

It should not be selected for heavy appliances solely because it is marked 20AX. Air conditioners, water heaters, pumps and motors can have different load characteristics, isolation requirements and starting currents. These loads may require a double-pole isolator, fused connection unit, contactor or dedicated control device. An electrical engineer should select the switching and protection equipment according to the appliance rating and UAE project requirements.

Contractors should verify model number BL114-885, two-gang one-way operation, 20AX rating, Starry Black finish, supply compatibility, terminal capacity, back-box requirements and coordination with the chosen ABB Inora range. They should also review the approved material submittal, load schedule, lighting-driver inrush data, local authority requirements and ABB's latest technical documentation before bulk procurement.

Isolate the electrical supply before maintenance. Clean the visible surface with a soft, dry or slightly damp cloth, and avoid abrasive pads, solvents, strong chemicals and excessive water that could damage the finish or enter the mechanism. If the switch becomes hot, loose, noisy, discoloured or intermittent, stop using it and have the circuit inspected by a qualified electrician rather than attempting an internal repair.
