Figures 2 and 4 of this patent show an adaptor plugged into what appears to be a "Chapman" receptacle. [3] Hubbell evidently soon found the round pin design unsatisfactory as a subsequent U.S. patent 774,251 filed on May 27, 1904 shows lampholder adaptors similar to those of his first patent for use with plugs having coplanar (tandem) flat pins.

Some types of connectors are approved for hazardous areas such as coal mines or petrochemical plants, where flammable gas may be present.
Hubbell had been one of the first to manufacture flush toggle switches for alternating current only. The first Safety Receptacle was designed and produced as were the original "grounding only" devices which helped to set the standards for the industry.

IEC 60309 (formerly IEC 309 and CEE 17, also published by CENELEC as EN 60309) is a series of international standards from the International Electrotechnical Commission (IEC) for "plugs, socket-outlets and couplers for industrial purposes".
This is a round plug compatible with CEE 7/1, CEE 7/3, and CEE 7/5 sockets. It has two round pins measuring 4.8 by 19 mm (0.189 by 0.748 in). The pins are not sheathed, in contrast to e.g. CEE 7/16 Europlugs. It may be rated at either 10 A or 16 A. A typical use is for appliances that exceed the 2.5 A rating of CEE 7/16 Europlugs.
