Cable Gland Accessories — IP Washers Locknuts Serrated Washers Banjo Tags
This article covers Cable Gland Accessories — IP Washers Locknuts Serrated Washers Banjo Tags. Cable gland accessories ensure correct IP rating and earthing for Ex equipment. This guide explains nylon IP washers, locknuts, serrated washers, and banjo earth tags — when each is required and why.
Overview
Cable gland and accessory selection for Ex equipment is a core topic in CompEx Ex01/Ex02 and is tested in the equipment selection simulator on EX Academy. Understanding the correct specification for every scenario — threaded vs clearance, Ex d vs Ex e, metal vs polyester body — is essential for the assessment.
EX Academy's 15 equipment selection scenarios specifically test cable gland and accessory selection across a range of Ex protection types, enclosure volumes, and gas groups. Scenario 01 (Ex d, 2.5L, threaded entry) is the recommended starting point.
Key Rules
Always verify: (1) entry type — threaded or clearance; (2) enclosure volume for Ex d; (3) enclosure body material for Ex e; (4) gas group — must match or exceed area classification; (5) accessories required for the specific combination of entry type and body material.
