This document discusses methods for providing basic protection against direct contact with live parts of an electrical installation. It outlines four main methods: 1) Insulation of live parts with material capable of withstanding mechanical, chemical, electrical and thermal influences. Paint or enamel alone is not sufficient. 2) Barriers or enclosures to prevent access to live parts, providing a minimum degree of protection. Openings are allowed if risks are addressed. Barriers must be securely fixed and withstand stresses. 3) Obstacles to prevent unintentional contact with live parts during normal operation, but can be intentionally circumvented. Only for use where access is restricted. 4) Placing live parts out of reach
