Provided is an electronic device and method for controlling the same, which controls an operation by detecting a voltage between a plurality of live terminals and thus determining whether there is an error in supplying power through a power input terminal. According to an embodiment, an electronic device includes a power input terminal including a plurality of live terminals and a neutral terminal; a voltage detection circuit connected between the plurality of live terminals for detecting a voltage between the plurality of live terminals; and a controller configured to control operation of the electronic device to be interrupted in response to a magnitude of the voltage between the plurality of live terminals smaller than a threshold.

An electrical connector is configured to couple an electrical conductor to a support surface. The electrical connector includes a terminal block having a connecting aperture, a threaded aperture, and a channel. At least a portion of the threaded aperture is positioned between the channel and the connecting aperture. The connecting aperture is configured to receive the electrical conductor. The electrical connector includes a fastener having threads receivable within the threaded aperture. The fastener is configured to secure the electrical conductor against movement relative to the terminal block. The electrical connector includes a lock receivable within the channel to inhibit unintentional movement of the fastener relative to the terminal block.

The invention relates to an electrical connection arrangement (4) for the electrical and mechanical connection of a first electrical conductor (2) to a second electrical conductor (3), having an electrical connection element (8) with a first end and with a second end, wherein a press portion (9) is arranged at the first end, the press portion having at least one lateral contact surface (11) for electrical contact with an inner lateral surface (12) of a contact recess (13) of the first electrical conductor (2), and wherein a bearing portion (10) is arranged at the second end, the bearing portion having a bearing surface (14) for non-positive connection to a side surface (15) of the second electrical conductor (3). A connection bore (16) extends at least between the bearing portion (10) and the press portion (9) so that the connection element (8) can receive a first fastening means (17) or forms a first fastening means (17) itself, and can receive a second fastening means (18) which can be connected to the first fastening means (17) so that the non-positive connection is produced between the bearing surface (14) of the bearing portion (10) and the side surface (15) of the second electrical conductor (3). It is provided that the press portion (9) can be radially spread apart by the first fastening means (17) and/or by the second fastening means (18) in order to bring about a non-positive connection between the at least one lateral contact surface (11) and the inner lateral surface (12) of the contact recess (13), by the two fastening means (17, 18) being connected together.
