The major limiting factor for 110V RLV circuits is generally believed to be voltage drop. However, in practice, ensuring the earth fault loop impedance (Zs) of the 110V RLV circuit is within the maximum permitted level usually represents the greatest challenge to installation designers. As stated above, BS7671:2008

The maximum earth fault loop impedance values (Z s) in BS 7671 – or the equivalent tables in the IET On-Site-Guide (OSG) and IET Guidance Note 3 Inspection and Testing (GN 3) – are essential references when carrying out Z s tests. Reduction in maximum values of earth fault loop impedance in BS 7671. One of the changes being introduced by BS 7671:2008+A3:2015 (IET Wiring Regulations Seventeenth Edition), which was published in January and comes into effect on 1 July, is a reduction of maximum values of earth fault loop impedance (Zs) in Tables 41.2, 41.3, 41.4 and 41.6.

Divide this value by the expected power factor of the 110V system and there's your earth fault loop impedance value.
