3.6 Installation regulations

In the

Federal Republic of Germany,

various national regulations for the

installation in explosive areas must be taken into consideration. The basis
being the ElexV complemented by the installation regulation DIN VDE
0165/2.91. The following are excerpts from additional VDE regulations:

DIN VDE 0100 Installation in power plants with rated voltages up to

1000 V

DIN VDE 0101 Installation in power plants with rated voltages above

1 kV

DIN VDE 0800 Installation and operation in telecommunication plants

including information processing equipment

DIN VDE 0185 lightning protection systems

The

USA

and

Canada

have their own regulations. The following are excerpts

from these regulations:

NFPA 70

National Electrical Code Art. 500 Hazardous Locations

ANSI/ISA-RP
12.6-1987

Recommended Practice

C22.1

Canadian Electrical Code
