WR1.HK / PRACTICAL GUIDE
All names, addresses, telephone numbers and technical values are fictional illustrations matching the six-page residential demo PDF. Start with Part 3, then review Parts 1 and 2. Customer details can carry into the tool; responsible personnel must verify registration and technical entries. No actual inspection or testing took place, so both inspection declarations remain unticked and all signatures and dates remain blank.

Fictional Kowloon home · One board · Four outgoing circuits
Fictional details · No inspection performed · Not an issued certificate63 A, 220 V and the circuit and device values identify this sample PDF only. They are not design or equipment-selection recommendations for your home.
Responsible person · Customer supplies details; the worker verifies the installation and owner particulars.
This example covers one residential flat. The enquiry contact may differ from the installation owner; do not substitute one for the other without checking.

Entry in this example
九龍示範道1號示範大廈8樓A室（虛構）
What to check：The Chinese text matches the demo PDF: fictional Flat A, 8/F, Example Building, 1 Example Road, Kowloon. Actual entries must identify the building, floor and flat consistently across drawings and records.
Entry in this example
陳示範（虛構）
What to check：The fictional Chinese name is retained from the PDF. Enter the actual installation owner; do not automatically substitute the enquiry contact or contractor.

The example is described by diagram (a) and the installation attachment
What to check：This describes the combined Part 3 information; it does not imply a separate official text box requiring this sentence.
Entry in this example
1 page
What to check：One separate single-line drawing, SLD-1. Do not count the two WR1 pages. Use the same count in the Chinese and English fields.
Entry in this example

The same fictional details are repeated only to show their positions. Actual design and inspection roles may involve different people and must be verified independently. Neither declaration is selected because this example was not tested.

Responsible person · An authorised representative of the REC relevant to this section.
Fictional entries are repeated for illustration. Verify this contractor and representative independently. The endorsement also includes the form’s statements about giving inspection records to the owner and retaining copies; it is not merely a stamp position.

These screenshots show the same fictional project. Supplied customer details carry into the draft. Personnel eligibility, technical entries and inspection conclusions still require verification.
Blank in this draft does not mean optional. Responsible personnel must complete the final document according to the actual work.
Download this residential sample PDF ↓Six-page Traditional Chinese PDF, about 4.8 MB. Inspection declarations, inspection dates and signatures remain blank.
Open the official EMSD blank form ↗
Page 1 contains Part 1 for design and Part 2 for installation, inspection and testing. Page 2 contains Part 3 for installation particulars. You can organise Part 3 first, before the responsible personnel complete Parts 1 and 2. The enquiry contact and installation owner may be different people.
Provide the full Hong Kong installation address, the owner’s name or organisation and contact telephone. Give a separate correspondence address if it differs. An example such as Flat A, 8/F, Example Building, 1 Example Street is fictional and must be replaced with actual details. Obtain authority before providing another person’s information.
The responsible worker prepares the installation description and/or diagram for the actual inspected scope and counts additional drawings and description sheets. Item (a) holds the single-line diagram; (b) identifies the inspected location and scope; (c) records the verified largest switching device rating, voltage and phase, deleting the inapplicable option. Do not guess values from a sample or a single circuit.
The REW responsible for design certification enters their name, registration number, expiry, grade, permitted works, telephone and signing date. For the REC entry, distinguish the authorised representative from the contractor and verify registration details. Design and inspection may involve different personnel; do not copy one person into both roles without checking.
The REW selects the applicable declaration: inspection of the installation described in Part 3, or inspection of only part with valid applicable WR1(A) certificates received for the other parts. Record the actual inspection date, separately from signing dates. Do not preselect conclusions or default to today. An authorised REC signatory endorses the record and confirms delivery and copy retention as stated on the form.
Customer submission → administrator review and assignment → reviewed partner accepts → worker opens the same project. Supplied address, owner and telephone details carry into the draft. Complete only missing or changed entries, verify personnel profiles, site details and circuits, preview the single-line diagram, then export an unsigned WR1 PDF.
Check the address, inspected scope, drawing counts, registration entries and dates for consistency. Do not certify uncompleted or unverified work. The tool does not store or apply signature samples. Its PDF leaves signatures blank for responsible and authorised personnel to complete after the required verification. Never pre-sign blank certificates or circulate reusable signature samples.
