Legrand Soliroc heavy-duty, protective frames
13 May, 2011Soliroc is a range of heavy-duty, protective frames to deter vandals from damaging wiring devices installed in exposed, public and unsupervised spaces. The metal alloy finish provides a strong resistance to scratches, graffiti and lighter flames. To deny unauthorised access to wiring devices, curved edges make it difficult to gain a firm grasp of the protective frame and plugs cannot be removed once installed. For additional security, there is also an option to have lockable flaps to cover the mechanisms.

Protecting against electrical surges - 20 things you should know
07 October, 2010 by Paul StathisAll electrical installations are subject to a frequently distorted electricity supply. Uncontrollable anomalies such as lightning strikes and electromagnetic interference can and do distort the AC supply into buildings. Some can be catastrophic, destroying equipment from a single surge, while others can be too small to notice on their own, but have a cumulatively detrimental effect on equipment that inexplicably fails over time. But there are simple ways to deal with these challenges.
