Type MCOS cables are oil-resistant portable cord type constructions suitable for flexing service. They may be used in electronic, communications and instrumentation applications except where unusual circuit parameters require a special type of cable. These cables are not watertight and shall be used only for runs within one compartment or within contiguous compartments. They shall not be used to penetrate a watertight deck or bulkhead.
