Talk:NEMA connector

NEMA-10

The article mentions (un)safety of the NEMA-10, in that the neutral could break or become loose. Since they were common for many years, and I believe grandfathered in current use, it would be interesting to know if anyone was ever electrocuted through this process.

straight

The article mentions the curved blades for twist-lock, which is at least slightly obvious. It then mentions straight blades otherwise. But many NEMA non-L connectors have other shapes. Some have a round or U-shaped ground pin. The 5-30, 10-30, and 14-30 have an L shaped pin. Somehow this needs to be discussed in contrast to the curved blades. Oh, some L connectors have a center round pin. Gah4 (talk) 22:15, 29 June 2020 (UTC) For the latter, the L21-30 has a round center ground pin. Gah4 (talk) 22:20, 29 June 2020 (UTC)

TT-30

This article stubbornly refers to the common RV connector as a NEMA TT-30. The TT-30 is not recognized by NEMA. I think is because the TT-30 closely resembles the NEMA 7-20 and 7-50 which are intended for 277V. For completeness, I suggest we document the TT-30 in this article but do not call it a NEMA TT-30.

The TT-30 is listed on page 145 of the ANSI/NEMA WD 6-2016 document (PDF page 153, available from archive.org [1]). It's listed in a table with heading "NEMA CONFIGURATIONS FOR SPECIFIC PURPOSE PLUGS AND RECEPTACLES", so as of 2016 both ANSI and NEMA seem to agree it is a NEMA TT-30. Or is there something more subtle here? Olawlor (talk) 05:45, 21 September 2021 (UTC)

Detachable

The article says, "When a power feed cord is detachable from an RV, an L5-30P is usually used on the RV end of the cord. " That is hard to believe. Almost certainly, at the RV end of the cord the connector would be a female ("receptacle" - "R").

I think today typical RVs (except the largest) have a TT-30P on the RV body, so the cord would have a TT-30R at the RV end. Doug Kerr

First, instead of writing your name, put in four tilde's. WP will then put in your name, date, and time.

Otherwise I suspect you are right, though it depends on how exactly you read the statement.

Even though it doesn't seem like it, it could mean the trailer side of the connection. This is a general problem when describing connectors, where it is sometimes easier to describe in terms of the mating connector. Gah4 (talk) 00:37, 31 October 2022 (UTC)
