A bus system which includes two or more voltage-to-current transformers, a common bus, a terminal bus coupled to a voltage source, two or more first switches, and a selection circuit. In some implementations, a method includes: automatically without human intervention, identifying a subset of side effect data associated with a set of enterprise data. In a first state it activates the first regulator when the detector detects a negative or positive output current, and in a second state it activates the second regulator when the detector means detect a substantially zero output current. In order to improve the repeatability of the operation for positioning the protection device, a guiding device is provided which includes an assembly element on the portion of the fixing device, and an element for guiding the protection device. Custom-built replacement body floors are thus used to successfully rebuild the off-highway truck body to specific applications with minimum effort. The hole communicates with a clamping surface of the jaw having the hole and a magnet is received in the hole.
