Ram air fan terminal stud

A ram air fan terminal block, comprising:

• a housing;
• a base having a plurality of slot walls that provide a slot;
• and
• a plurality of terminal studs each having a threaded portion extending from a head, the head received within the slot and the threaded portion extending through an aperture in the base, wherein the head has a sidewall that interfaces directly with one of the plurality of slot walls, and a ratio of a length of the sidewall to a height of the sidewall is from 2.18 to 2.35, wherein the head has an endwall that is generally perpendicular to the sidewall, the endwall having a width that is less than the length of the sidewall.

A method of electrically coupling a ram air fan assembly motor to a controller, comprising:

• (a) torquing a threaded fastener to a terminal stud to hold a lead of a ram air fan motor in an electrically coupled position with a lead of a controller;
• and
• (b) contacting a sidewall of a head of the terminal stud to limit rotation of the terminal stud during the torquing, the sidewall having a length and a height, wherein a ratio of the length to the height is from 2.18 to 2.35,
• wherein the head has an endwall that is generally perpendicular to the sidewall, the endwall having a width that is less than the length of the sidewall.
