Llamacoids / Lamacoid FAQ / Section 64 solar labels
CEC Section 64 solar labels. What a PV install has to mark.
Section 64 of the Canadian Electrical Code (CSA C22.1) asks solar PV installs for permanent marking at every PV disconnect, the utility interconnection, the DC disconnect or combiner, the grounding point and, where adopted, rapid shutdown. The PV warning sign is white letters on red, in capitals, at least 9.5 mm tall. Check the code edition your province has adopted.

Which Section 64 rules call for marking?
Six rules cover most of the plates on a PV install. The rule numbers below follow CSA C22.1 Section 64; check them against the edition your province has adopted.
| Rule | What gets marked |
|---|---|
| 64-060 | Every PV disconnect, marked with what it serves. |
| 64-072 | AC voltage and current at the utility interconnection. |
| 64-200 | PV warning sign: white on red, capitals, minimum 9.5 mm letters. |
| 64-202 | Maximum PV voltage at the DC disconnect or combiner. |
| 64-064 | Permanent marking at the grounding point. |
| 64-218 | Rapid shutdown, at the meter and the service, where adopted. |
What colour and size is the PV warning sign?
White letters on a red background, in capitals, at least 9.5 mm tall, under Rule 64-200. On a lamacoid that is a red/white plate with 3/8" lettering, which clears the minimum. Red/white is a stocked colour.
What plates does a typical solar install need?
It depends on the system and the jurisdiction, but most kits include the same core set. Tell us the province, the system and the inverter, and the kit is worked out from that.
- Inverter warnings
- AC and DC disconnect plates
- Rapid-shutdown switch and RSD panel notices
- PV output data plate
- Grounding point tags
- DC conduit warnings
- Combiner box ID
- Dual-source warnings
- A single line diagram plate, from the builder's solar kit
Does Ontario follow CEC Section 64?
Yes. Ontario adopts the Canadian Electrical Code as the Ontario Electrical Safety Code (OESC), enforced by the Electrical Safety Authority (ESA). Each province adopts the CEC, sometimes with changes, so the edition and any local amendments decide the exact requirement. Rapid shutdown marking applies where it has been adopted.
Do engraved placards meet the permanent marking requirement?
The code asks for marking that is permanent and legible. On an engraved lamacoid the letters are cut through the red surface to the white core, so there is no ink to fade on a roof. The installer, the engineer and the inspector remain responsible for compliance; Llamacoids makes the placards and does not certify or inspect installations.
How do I order a Section 64 placard kit?
Send the single line, the equipment list or phone photos, and say which province the job is in. A same-day quote comes back line by line. Or fill in the system once in the Lamacoid Builder solar kit and get the single line diagram plate plus every placard the install needs, in English, French or both.
Placards come pre-drilled or with 3M VHB adhesive, bagged and labelled per placard, with an install diagram. Solar placard kits →
