Meter Locking Rings vs. Ringless Meter Locks
Ringless meter locks and meter locking rings do the same thing: they prevent tampering and theft of service. Besides their shape, the difference is how they’re installed on the electrical enclosure box.
For ring-style metering devices, the enclosure cover is installed before the metering device is installed on the meter socket base. A ring secures the metering device in place by attaching to the meter housing and the meter curl (the raised rim around the opening in the cover).
With the electric meter box cover installed, the installation process is safer for electricians. In the event that an electrician’s hand slips during installation, the cover will prevent contact with live wires.
For ringless metering devices, the metering device is installed before the cover. Then a ringless locking mechanism is secured to the cover on the side, bottom, or both. The advantage to this approach is that working with the cover off allows the electrician to identify short circuits and other equipment defects prior to meter installment.
In either case, the locking device protects the electric meter against tampering and electricity theft.
