Cables, power requirements & consumption

415V, 3-phase, 32Amp. (UK and Europe)

480V, 3-phase, 32Amp. (Canada and USA)

Earth & neutral required (5 pin plug).

Power consumption: 28KVA (22 Kw/hr) only during operation. 

The Etorch 3 is connected to the control box by a 5m sleeved hose. The control box features a 5 pin 32A male plug connected by a 4m cable. A 20m extension cable is supplied to allow the control panel to be connected to the main 

3-phase power supply.

To reach longer distances to power sources further extension cables at 20m and 40m are available to purchase.

Mains monitor relay is included in the control panel to protect against external power issues.

Note: For use on site without a permanent fixed supply we recommend using a 30KVA site generator with a 32amp five pin plug fitting (Red & white plug). If the generator has a 64amp plug an adapter is available to purchase to fit the 32 amp cable plug.
