1 Scope

This section GB/T 2820 provisions by reciprocating internal combustion (RIC) engine driven generating sets with control means and switching means Claim.

This section applies to the reciprocating internal combustion (RIC) engine driven land and marine AC (a.c.) generator sets, does not apply to aviation or flooding Moving land vehicles and locomotives generators.

For some special purposes (such as hospitals, high-rise buildings essential power supply), additional requirements may be needed. The provisions of this section it can be used as the basis to determine any additional requirements.

For other types of reciprocating by a prime mover (such as a steam engine) driven alternating current (a.c.) generator sets, the provisions of this section may as a basis.
