Ethos Electrical Circuit Schedule 12 Way Test Details

Critical Documentation for BS 7671 Electrical Installation Testing

The Ethos Schedule of Circuit Details and Test Results 12 Way form is an essential compliance document designed specifically for electricians conducting initial verification and periodic inspection testing of electrical installations. Aligned with BS 7671 A2 2022 Standards, this schedule is designed to accompany electrical installation certification and is suitable for distribution boards and consumer units with up to 12 ways.

Why This Form Matters for Your Testing Work

The validity of an Electrical Installation Certificate is only assured when it has the accompanying documentation, including a Schedule of Test Results and a Schedule of Inspections. This schedule is that critical supporting documentation. BS 7671 specifies a systematic testing sequence including dead tests (continuity, ring circuit, insulation resistance, polarity) followed by live tests (Zs, PFC, RCD trip times). This form provides the structured format to record all those test results accurately.

Comprehensive Circuit Documentation

Unlike generic notepads or incomplete forms, this 12-way schedule allows you to document complete circuit details including conductor specifications, overcurrent protective devices, RCD information, and test measurements for each circuit. The form layout mirrors the exact data requirements specified in BS 7671, reducing errors and ensuring regulatory compliance without guesswork or missing fields.

Who Needs This Form

This schedule is essential for electricians holding the appropriate inspection and testing qualifications (C&G 2391-50, 2391-51, or 2391-52) conducting either initial verification of new installations or periodic inspection and testing (EICR) of existing installations. Whether you're certifying new work, recording circuit alterations, or documenting periodic maintenance inspections, this form becomes part of the permanent electrical safety record for the building.

BS 7671:2018+A2:2022 Compliance

BS 7671, also known as the IET Wiring Regulations, is the UK's national standard for the design, erection and verification of electrical installations, bringing together European and international standards to provide a single, authoritative reference for safe, compliant electrical work across domestic, commercial and specialized environments. Using the correct Ethos forms ensures your documentation meets these mandatory standards and provides clear evidence of compliance during inspections or audits.

Key Technical Details

The form includes dedicated sections for recording maximum measured values, test voltages, circuit conductor details, protective device specifications, and earth resistance measurements. The 12-way capacity makes it ideal for small to medium residential installations and commercial distribution boards, accommodating the most common circuit configurations found in UK electrical work.

Professional Record Keeping

This is not simply a worksheet—it becomes part of your client's electrical safety record and demonstrates professional compliance with legal requirements. The structured format ensures no critical test data is overlooked, and the consistent layout makes records easy for other electricians or inspectors to review quickly.
