Yes, CEE 16A and CEE 32A sockets differ significantly in power capacity, physical dimensions, applications, and cabling. The most important distinction is the maximum current each can handle: a CEE 16A socket supports up to 16 amps, while a CEE 32A socket is designed for 32 amps. This means a CEE 32A connection can deliver nearly double the electrical power, which is essential for high-demand applications such as industrial machinery or fast charging of electric vehicles.

Physical size and compatibility

One of the most noticeable differences is the physical size of the plug and socket. A CEE 32A socket is substantially larger and sturdier than a 16A socket. The 32A version typically has an outer diameter of around 70 mm compared to approximately 50 mm for the 16A. The pins are also thicker and spaced further apart. These differences are intentional to prevent mismatching: a 32A plug will not fit a 16A socket and vice versa, improving safety for higher-power connections.

Technical capacity and cabling

A CEE 16A socket is usually used for 230V (single-phase) or 400V (three-phase) applications and can deliver up to 11 kW. The CEE 32A socket can deliver up to 22 kW, making it ideal for more power-intensive setups like the Voldt Type 2 mobile charger with CEE 32A plug. This also means thicker cabling is required — typically 6 mm² for 32A vs. 2.5 mm² for 16A — to handle the higher current safely.

Applications and installation

CEE 16A sockets are common in camping grounds, garages, or for lighter mobile uses. CEE 32A sockets are used in industry, food trucks, construction sites, or high-capacity EV chargers. Their larger size means they’re also physically more robust and often waterproof (IP44 or IP67). Proper installation in the UK must include appropriate fuses and RCDs in line with BS 7671 wiring regulations.
