Pat Testing Electrical Test Tools

In addition to its specialist electrical safety testers‚ Seaward provides a range of general purpose electrical test tools‚ testers and equipment used by electricians‚ electrical technicians‚ test engineers and industrial maintenance personnel.

These handy testers and accessories are a must for all electrical installation and engineering tool boxes, giving users the ability to deal immediately with a wide range of day to day electrical safety testing applications.

  • Voltage Detectors - Voltage testers are a staple requirement of the professional electrician’s toolkit.
  • Proving Units - Wherever electrical safety depends on the ability of a test instrument to indicate if a circuit is live or isolated‚ best practice demands that the test device is checked before and after use.
  • Discharge Units - Ensuring that electrical systems are safe to work on is a pre-requisite in a wide range of industrial maintenance and power sectors before maintenance or testing is undertaken.

Installation Testing

The 17th Edition of the IEE Wiring Regulations (BS7671) is the national standard to which all domestic‚ commercial and industrial fixed wiring installations must conform. Part P of the UK Building Regulations also requires certain safety testing and inspection requirements on certain domestic electrical installations.

To comply with these requirements electricians, need to be able to carry out a wide range of safety tests on fixed electrical wiring circuits and provide a formal Electrical Installation Certificate, together with a schedule of test results and inspections undertaken.

The Seaward installation test range is designed to enable electrical contractors to carry out electrical safety testing to the highest possible standards. Advanced multifunction electrical testers and application specific testers are available that combine ground breaking technology with practical design features for trouble free 17th Edition and Part P electrical testing.
