Last month, one of our members’s contribution had told you how to work around LV systems as an electrical engineer. Now enjoy the part 2 with more details…


Low electrical voltage is any voltage at or below 750V. In some regions, it can be used to define extra low voltage that is at or below 1000V. Common low voltage areas include residential utility lines, as well as light industrial application. With proper precaution, working around LV is safe. However, as with all matters electricity, sometimes things go horribly wrong. The following are key problem LV areas.

Working Alone

In most of the cases, small projects only require a solitary person to sort it out, to reduce the interruption of routines that result from switching off the mains. Danger abounds in working alone, regardless of the size of the project.

While space restrictions and number of staff may deem working alone a necessity, there are some measures that should be adopted. They include the following:

  • Clear written procedure for checking on someone working in isolation
  • Emergency responses in case the worker cannot be contacted, especially those working on the rooftops or underground
  • Clear liaising on the check up times. This should be done between the engineer in charge, the person designated for the check up and the worker in isolation
