ABB Inora 2 Gang 2 Way 20AX Switch White BL115

Two gang means the switch has two separate rockers for controlling two lighting circuits from one wall position. Two way means each circuit can also be controlled from a second location when paired with another compatible two-way switch and correctly wired using common, L1 and L2 terminals. This arrangement is commonly used in staircases, corridors, halls and rooms with more than one entrance.

The 20AX marking indicates a switching rating intended for lighting loads, including certain loads that can produce higher starting or inrush currents than standard resistive loads. The actual permissible load depends on the lamp type, LED driver, ballast, power factor and manufacturer data. An electrician should verify compatibility rather than selecting the switch only by total lamp wattage.

It can generally be used as an on/off control for compatible LED lighting circuits. However, LED drivers may create significant inrush current, especially when several fittings are connected to one gang. The circuit designer should check the combined driver characteristics, switching capacity and protective device requirements. This is a mechanical switch, not an LED dimmer.

The switch is suitable for indoor residential, commercial and light-construction applications such as villas, apartments, offices, shops, corridors, staircases and hotel rooms. Its two-gang layout helps control two lighting zones from one point, while its two-way function is useful where lights must be operated from two positions.

For each gang, two-way control normally requires a compatible switch at each operating point, with the permanent live and switched live connected through the common terminals and two strapper conductors connected between L1 and L2. The exact terminal arrangement must follow the wiring diagram and markings supplied with the product. Power must be isolated, locked off where applicable and proven dead before installation.

Yes. A two-way switch mechanism can normally be used for one-way control by using the common terminal and the appropriate L1 terminal for each gang. The unused terminal remains unconnected. Wiring should be completed by a qualified electrician according to the product terminal markings, circuit design and applicable UAE electrical requirements.

Use a compatible flush or surface mounting box with sufficient depth for the switch mechanism, conductors and terminal bends. Box compatibility should be checked against the ABB Inora product dimensions before installation. Suitable screws, approved cable, insulated conductors, connectors and an appropriate circuit protective device are also required. Avoid forcing excess wiring behind the switch, as this can loosen terminals or damage insulation.

Use in bathrooms, wet areas, outdoor locations or exposed service zones depends on the complete installation's ingress-protection rating and local zone requirements. A standard indoor wall switch should not be assumed to be weatherproof. For balconies, gardens, wash areas or dusty construction environments, install a suitably rated weatherproof enclosure or select a dedicated IP-rated switch.

Installation should comply with the applicable requirements of the relevant UAE authority, such as DEWA, ADDC or the local electricity and building authority, together with the project's approved specifications. Wiring practices commonly reference BS 7671 and relevant IEC standards where adopted. A licensed electrical contractor should confirm circuit protection, conductor size, earthing, mounting location and inspection requirements.

The BL115 is primarily intended as a lighting switch. Fans, motors and other inductive equipment can have starting currents and isolation requirements that differ from lighting loads, while socket outlets require accessories specifically designed for that purpose. Do not use this switch as a substitute for a socket, motor isolator or heavy-duty appliance control unless ABB documentation and the electrical design explicitly permit the application.

Contractors should verify correct common, L1 and L2 connections; independent operation of both gangs; proper two-way switching from each location; secure terminal torque; conductor identification; insulation integrity; polarity and circuit protection. The faceplate should sit level without trapped cables or exposed copper. Required continuity, insulation-resistance and functional tests should be recorded according to the project method statement and local regulations.

Clean the faceplate with a soft, slightly damp cloth after isolating the circuit if necessary. Do not use abrasive pads, solvents or aggressive construction chemicals. During handover and planned maintenance, check for discoloration, cracking, loose operation, buzzing or excessive warmth. Any damaged or overheating accessory should be isolated and inspected by a qualified electrician.

The ABB Inora BL115 combines two separate lighting controls in one white wall accessory and supports two-way switching for flexible room, corridor and staircase layouts. Its 20AX lighting rating can suit demanding lighting applications when correctly matched to the connected equipment. Contractors should confirm dimensional compatibility, load characteristics and authority approval before procurement.
