Local codes of practice or regulations may be in force to ensure that safety is maintained to eliminate the possibility of accidents arising from the danger of electricity. These dangers would include electric shock, burns, fire, explosion and arcing. In the United Kingdom the ESQCR 2002, and amendments 2006 (S.I. No. 1521) and 2009 (S.I. No. 639), introduced under Statutory Instrument No. 2665, and the Electricity at Work Regulations 1989 (EAW Regulations), which came into force on 1 April 1990, comprehensively deal with this subject.
Read moreEMC Performance
Tests were carried out in an anechoic chamber using various CMP cable glands with a section of cable connected to it which would act as an aerial. A known electrical radiation source was used to introduce interference into the chamber, and the level of radiation in the cable shield was measured.
