Another tamper resistant question

[Jim Robinson]

Is a single 120 volt dedicated receptacle now required to be TR as well as the duplex variety? I am asking because of my washing machine receptacle in our new laundry room. It is not currently TR, and we'll probably put the machine in place in the near future.

Yes.

From the 2008 NEC. (underlining, bold, red text is mine)

- - In all areas specified in 210.52, all 125-volt, 15- and 20-ampere receptacles shall be listed tamper-resistant receptacles.

- 210.52 Dwelling Unit Receptacle Outlets.(Note: All I am posting are the main sub-headings, all of which are "as specified in 210.52".)

Except for receptacles installed on the roof (for servicing equipment) and any installed in an attic, receptacles in a dwelling unit are required to be tamper-resistant. It doesn't matter if you're replacing an existing or doing new work.

Unless you have a local ordinance requiring it there is no reason to have a simplex (single) receptacle in the laundry. Things like irons and clothes steamers are allowed to use the same circuit.
