Abstract: An electrical connector arrangement for a turbomachine includes a support structure and a terminal with a terminal post projecting from the support structure along an axis. The electrical connector arrangement includes a connection stack that is supported by the terminal and arranged along the axis of the terminal post. The connection stack includes a bus bar that is electrically connected to the terminal post and that extends from the terminal post and the support structure. The connection stack includes a first deformable seal member and a second deformable seal member. The first deformable seal member is deformed against the terminal post to define an inner radial seal within the connection stack. The second deformable seal member is deformed against the support structure to define an outer radial seal within the connection stack.
