As per the UK Highways Traffic Sign Manual Chapter 4 - Warning Signs page: 79 The following advice is given:

20.2.1.  Diagram 779 (S2‑2‑54, see Figure 20-11) warns of a place where a road passes under an electrified overhead power cable. It must always be accompanied by a plate indicating the safe maximum height vehicle that can pass below the cable (see Figure 20-12, Figure 20-13 & Figure 20-14). These signs are normally associated with overhead electric railway or tramway cables and should be used at all such crossings. Because of the high voltage of certain cables, it is very important to ensure that adequate warning is given even where cable heights are greater than 16’‑6” (5.03 m).fic.
