Why You Can't Buy an IEC 60309 Power Strip
Daniel terminated his first IEC 60309 connector — the blue 16A industrial plug known as commando, pin and sleeve, or CeeForm — and it worked. But two questions remain: what cable actually belongs on a 16A connector feeding a device that would run fine on a lamp cord, and why can't you buy a bench strip or PDU with these outlets? The cable answer is counterintuitive: you size the cable to the connector, not the appliance, because the circuit is defined by the plug and its breaker, not by whatever you happen to plug in. The market answer is stranger — the multi-outlet product Daniel went looking for doesn't appear to exist, and the reason is baked into what IEC 60309 was designed to do.
