Martindale MARVI13800
Voltage Indicator
Product Overview
The Martindale VI13700 has been widely used for many years and as part of its design has always included a fuse in the probe to limit the current in the event of damage to the cable.
There is a technical argument that fuses in a voltage indicator can cause unreliability and any problem with the fuse could cause the voltage indicator not to indicate a hazardous voltage. In reality this risk is very small and correct proving procedures will identify the problem. None the less, because of this potential problem, BS EN61243-3 prohibits the use of fuses in 2 pole voltage indicators.
NB Proper proving procedures should always be used with any voltage indicator.
