Key Specification Ratings
Maximum Continuous Operating Voltage (MCOV) – 6.0/10
Why Did It Earn this Score? – To put matters lightly, we are rather disappointed in Leviton’s method of communicating MCOVs to its prospective buyers of the 51110-SRG model. To be specific, we can hardly believe that this model operates a 150 amp MCOV across all three of its modes of protections. Either way, Leviton’s lack of specificity in the domain makes it all but inevitable that they would lose points here.
Voltage Protective Rating (VPR) – 6.0/10
Why Did It Earn this Score? – Here again, we struggled to isolate the Leviton 51110-SRG certified VPRs. We can see why Leviton may have tried to hide these specifications, though, because they appear to only clock in at a measly 400 and 600 amps respectively. Leviton doesn’t specificy which modes these VPRs correspond to, but regardless, they are rather meager for a unit that is expected to be installed outdoors.
Mode of Protection – 8.0/10
Why Did It Earn this Score? – For a model that only costs around $40, we were fully surprised to see that the Leviton 51110-SRG offered three differentiated modes of protection. Accordingly, prospective users will have the opportunity to use L-N, L-G, and N-G modes while working to install and operate their new surge protection system. Each mode also operates with an equal degree of efficiency, ensuring that you don’t lose out on protection capacity based upon your chosen mode of protection.
The Final Verdict
When it comes down to it, we can’t help but feel a little let down by the Leviton 51110-SRG. While it certainly performs well when it comes to durability and value, it’s difficult to say with certainty that it can meet its 26,000 amp protection capacity due to its lack of quantitative specifications. As such, those who choose to use the Leviton 51110-SRG should do so only after they have ensured that they can make full use of its 5-year warranty.
