AMF / Synchronizing Panel
Automatic Mains Failure panel switches load from mains to DG set (and back) automatically on power failure. Synchronizing panels allow multiple DG sets / mains-DG to run in parallel.
| Voltage Rating | 415V AC, 3-Phase, 50 Hz |
| Current Rating | 100A to 4000A depending on DG/mains capacity |
| Standard Sizes (H x W x D) | 2000-2200 x 600-1000 x 600-800 mm |
| Switching Device | ATS / Motorized ACB or MCCB with interlocking |
| Controller | DG synchronizing controller with load sharing |
| IP Rating | IP42 / IP54 |
| Typical Applications | Hospitals, data centers, factories, buildings with DG backup or multiple generator sets. |
Metering Panel
Dedicated panel for energy metering (CT/PT operated or direct), often used at utility handover points or for tenant sub-metering in commercial buildings.
| Voltage Rating | 415V AC / 11kV (HT metering with CT-PT unit) |
| Current Rating | As per CT ratio selected (e.g., 100/5A to 2000/5A) |
| Standard Sizes (H x W x D) | 800-1200 x 600-800 x 600 mm |
| Metering Type | Direct / CT operated / CT-PT operated (HT) |
| Accuracy Class | 0.2S / 0.5S as per billing requirement |
| IP Rating | IP42 / IP54 |
| Typical Applications | Utility handover points, tenant billing, industrial energy audits. |
Feeder Pillar
Outdoor, weatherproof panel used to distribute power from an underground cable network to multiple outgoing feeders, typically for street lighting or area distribution networks.
| Voltage Rating | 415V AC, 3-Phase, 50 Hz |
| Current Rating | 200A to 800A incomer |

| Mounting | Free-standing, outdoor, plinth mounted |
| Cable Entry | Bottom entry, underground cable |
| IP Rating | IP55 / IP65 (weatherproof, outdoor rated) |
| Typical Applications | Street lighting networks, township/campus power distribution, outdoor installations. |
Bus Duct / Busway
Enclosed, pre-fabricated conductor system used for carrying large currents between panels, transformers and switchgear as an alternative to cabling, offering compact and safe power transmission runs.
| Voltage Rating | 415V AC / 11kV (segregated phase busduct) |
| Current Rating | 800A to 6300A |
| Standard Sizes (Cross-section) | Custom per run length; standard length modules of 2-3 m |
| Type | Sandwich type / Air insulated busduct |
| Conductor | Aluminium or Copper, tin/silver plated |
| IP Rating | IP54 / IP55 |
| Typical Applications | Transformer-to-panel connections, riser risers in high-rise buildings, generator interconnections. |
