Merge discussion

Instead of merging the part at IEC connector, I suggest that we make this the main article for the heavy-current and polyphase devices, with a very short summary at IEC 60320 article. --Wtshymanski (talk) 14:46, 28 April 2011 (UTC)

Assuming this reffers to some proposal to merge IEC 60309 and IEC 60320 articles I agree such a propsal would be crazy. While there are some simlarities (both define inlets, outlets, plugs, couples etc) they are very different connectors for very different applications. Plugwash (talk) 03:17, 7 June 2011 (UTC)

Actually the opposite was the case. Content about IEC 60309 was merged here from IEC connector enabling a rename to IEC 60320 Lmatt (talk) 04:44, 7 June 2011 (UTC)

Neutral pin

for 2P+E connectors the standard talks of a live pin, a neutral pin and an unlabeled pin (or words to that affect it's been a while since I read it). Reading between the lines it sounds like they made the final pin unidentified because depending on the supply type it may be either a neutral or a second live but I can't seem to find anything that explicitly states that.

The distinction comes about because some installations use a split voltage system. For example in Europe, the 2P+E yellow plug is often used on building sites etc. with the supply derived from a transformer that supplies 55-0-55 volts. Thus there are two phase pins and no neutral. A similar situation arises in the US where even domestic supplies are usually provided at 120-0-120 volts allowing larger appliances such as cookers (incorrectly called 'ranges' in the US) and air conditioners to operate from 240 volts. 86.182.103.115 (talk) 17:05, 10 June 2011 (UTC)

Right, that was what I kind of figured, what puzzles me is why the standard doesn't actually seem to say anything about this... Plugwash (talk) 22:31, 11 June 2011 (UTC)

Grey connector @8h

The grey connector with PE@8h is suitable for DC with >250V and not limited to 250V. 86.103.172.240 (talk) 13:11, 24 August 2012 (UTC)

The standard states >250V DC. It is not helped because people who reproduce charts showing the various combinations don't seem the understand the significance of the '>' symbol and omit it. I have even seen a couple of charts that incorrectly list it as 250 volts AC. I B Wright (talk) 14:30, 1 December 2013 (UTC)
