Is there a reason why all conventional domestic electrical wiring fittings use exclusively slotted screw heads, rather than the much more practical Phillips or Pozidrive heads? Don't tell me that electricians can only carry one screwdriver?

Cross-headed screws enable assemblies to be made by machine. IIRC, Phillips are intended to slip when the required torque has been reached; Pozidrive accept a higher torque. If you really want positive engagement, specify Torx.
