Why do we carry out safe isolation?

Safe isolation has long been a procedure carried out by a competent person in order to safely isolate electrical circuits or equipment before electrical work is undertaken. Despite this, every year people within the construction industry suffer electrical shock and serious burns of which some are sadly fatal.

Ventilation Systems

Fitting extraction fans and ventilation systems has long formed part of the work carried out by electrical contractors. It is commonplace to install extraction fans in walls, cooker hoods, or even complex whole-house systems on a new build property.

Since the introduction of Part P building regulations in 2005, the technical performance of extraction equipment and also the areas in which it is to be installed needs consideration to ensure Part P compliance.

Whilst looking at different specifications of test equipment, I’ve come across the phrase ‘ramp test’. I know this has something to do with testing RCD’s, but what is a ramp test?

Question:

Our company use a fleet of Megger MFT1720 multifunction testers to complete inspection, testing and certification of both new and existing electrical installations. However, when we carry out a loop test at the same socket outlet, each tester displays a varied reading which may differ by 0.20 Ohms. Why is this when the make and model of each tester in use are identical?

Latest proposals by the Government designed to give employers more control over what their apprentices learn could end up causing more harm than good.

The Kewtech KT65DL Multifunction Tester is the most advanced multifunction installation tester within the Kewtech range and arguably the most complete ‘all-in-one’ solution on the market. The KT65DL will cover all aspects of installation testing including a three wire earth resistivity test, but also doubles up as a PAT tester for testing portable appliances to the recommended minimum requirements.

The Metrel MI3000 Easi Plus Multifunction Tester is the entry level multifunction tester within the Metrel range. The MI3000 boasts a impressive specification for a tester within this price range, offering test features that will satisfy not only domestic, but commercial and industrial electrical installations.
