Safe Isolation

To be able to work safely and effectively, electrical engineers require the best tools to protect themselves against serious injury. Safe isolation kits and accessories are a vital part of these safety measures, as safe isolation is the mechanism of isolating an electrical installation from the rest of a circuit, disconnecting it, and testing it to ensure there is no current flowing through it.

But with stretched budgets and high workloads, many engineers go without safe isolation kits in order to save money.

At Test4Less, we stock a wide range of great value safe isolation kits, lockout kits and voltage testers that can be used on virtually any electrical installation. Manufactured to the highest standard they can be relied upon to eliminate the risk of shock or electrocution and are accessible at a range of price points to suit any finance level.
