Awarded the Innovative Test and Measurement Product of the Year in 2014, the Safe Isolation kit has been modified and improved over the past few years with the latest model being their best yet. The most noticeable improvement is the change to molded guards on the voltage detector poles. The previous version had removable screw covers, which can prove to be an issue as they can get lost very easily.

There is also a modification on the proving unit as now there are lights to show the presence of voltage on proving unit (>50v), where the previous version didn’t, which meant if you had no relevant voltage it could confuse the results.

It’s imperative you fully read and understand the instructions. As if you don’t, we have found when you go to neutral on bottom of mains switch to neutral bar (incorrect procedure), it will do a continuity test automatically and self diagnostic test will be initiated and it will show up 690v, when there is no voltage present. This is down to user error and not manufacturer.

The Kewlok universal lock off kit completes this safe isolation kit perfectly and is quick and simple to use on site, while providing good termination. It fits most MCB’s and also toggle type main switches. The combination padlock provided means there’s no chance of you losing keys and it also comes with two reusable warning tags to be secured on.

All three items come in a handy carry case, with a back pocket for the instructions and your lock off kit. You will notice that the case has two holes punched in the transparent window of the bag. This both protects the proving unit and allows you carry out tests without hassle.

Pros:

• Molded guards on the two poles of the detector
• Lights to show the presence of voltage and warning light
• Handy, robust carry case with holes punched in the plastic for use of the proving unit
• Can be used on commercial as it goes up to 690v

Cons:

• LED check can initially confuse user if haven’t read the instructions. But this is down to user error, not manufacturer, and stresses the importance of reading the instructions before using the KEWISO2.

The KEWISO2 safe isolation kit is available to buy from Screwfix and various other online retailers.
