NFPA 70E Approach Boundaries to Live Parts | Dust accumulation and removal technology

[Information Technology and Solar Solutions]

Approach Boundaries of photovoltaic systems would be different for
traditional inverters | macro-inverters or micro-inverters based on
the nominal voltage. For traditional inverters, would be:

2004 NFPA 70E Standard for Electrical Safety in the Workplace® would
be Table 130.2(C). For photovoltaic systems (PV) ~< 600 DC Volts be a
Hazard Category of 0 when working on or near exposed live parts 2*,
with V-Rated Gloves and Tools with the Flash Boundary of 4 feet the
Limited Approach of 3 foot 6 inches, Prohibited Approach of 1 inch and
Restricted Approach of 1 foot.

A question came up in class with regards to dust accumulation and
removal technology would suggest for consideration.
