AI Customer ServiceProtection against electric shock under single fault conditions casing). Protection under normal conditions is achieved by basic protection, formerly known as protection against direct contact. Protection under single fault conditions is achieved by fault protection and was previously referred to as protection against indirect contact.
Protection against electric shock requires the provision of an appropriate measure of protection against direct contact and one against indirect contact, selected from those recognized by BS 7671 This topic covers the principles underlying the recognized measures of protection.
Chapter 41: Protection Against Electric Shock Contains methods used to reduce the risks of electric shock within an electrical installation and covers both methods of basic and fault protection, as such you’ll find the maximum Zs tables ie (T41.3 pg 56) are within this chapter.

Backfeed protection is an essential safety mechanism against dangerous electric shocks and arc flashes as outlined in the quality standard BS EN IEC 62040-1:2019 Uninterruptible Power Systems (UPS): General and Safety Requirements for UPS. Backfeeding refers to the flow of electricity in the reverse to its normal direction of travel.
External backfeed protection devices come in the form of a motor-operated circuit breaker or magnetic connector. Clear warning labels stating “Hazard Of Electric Shock, Explosion, Or Arc Flash” must appear on all switchgear access points and switching devices between the UPS and the external isolator.
