“Construction” Extension Lead

Cord Length:50m


Construction Extension Lead:

For indoor, outdoor and harsh environments.

The “construction” lead has a larger diameter cable and longer maximum allowable length from the outlet to the appliance than heavy-duty leads. It is suitable for use on sites that have a few 3 phase outlets, or the lead is connected to a temporary site power board that is a long way from the local distribution board. Where voltage drop is a consideration (either the machine is a considerable distance from the main distribution board or has high starting current).

The for the determination of the maximum cable length the outlet is assumed to be 25m from the main distribution board.

Maximum Continuous Length for general use: 110m

The maximum length for use with any equipment that has a high starting current:40m

The leads have the option of being tested and tagged ready for use before dispatch.
