Duplex receptacles at 15A / 125V in both decorative and standard bodies, tamper resistant where code requires it, supplied in ten and thirty piece contractor packs. A 30A 250V three pole four wire dryer receptacle covers the appliance circuit.
Tamper resistance is the default expectation on residential work now, so TR and non-TR are listed as separate SKUs rather than as a variant. Substituting one for the other is a code problem rather than a preference, and the page states which is which.
Pack size is the real differentiator: the thirty piece carton serves contractor and multi-unit work while the ten pack holds the retail facing. Sits on the same wall as wall plates, switches and GFCI.
