What the regs say
Running data and power in a single cable is a concern for many electricians. However, it is common in many existing applications. DALI networks combine power with data in a single five core cable.
Voltage Band I is defined as levels of voltage which are too low to provide serious electric shocks; effectively this limits the band to extra-low voltage (ELV), including telecommunications, signalling, bell, control and alarm circuits.
Voltage Band II covers all voltages used in electrical installations not included in Band I. This means that all 230/400 V (240/415 V) supplies are included in Band II.
528.1 Proximity of electrical services (extract)
Except where one of the following methods is adopted, neither a Band I nor a Band II circuit shall be contained in the same wiring system as a circuit of nominal voltage exceeding that of low voltage, and a Band I circuit shall not be contained in the same wiring system as a Band II circuit.
(i) - Every cable or conductor is insulated for the highest voltage present.
528.2 Proximity of communications cables (extract)
NOTE 1: Special considerations of electrical interference, both electromagnetic and electrostatic, may apply to telecommunication circuits, data transfer circuits and the like.
The data cables within EV Ultra are screened and twisted pairs to reduce interference.
