I don't believe it will "condition" the power, but it will typically work for low & high voltages, open neutrals and grounds, and surges. JM2ยข...
There are two types of Surge Guards... And your statement is correct for the good ones. (More after I answer the Original Poster's question)
To the Original poster: The answer is YES, not only will it work, but one if it's functions will work BETTER on a smaller power feed..
Now to both: Low cost "Surge guards" are simply spike supressors. they are little more than MOV (metal Oxide Varisistors) and do a very good job of clipping spikes that come along when say an air compressor cuts out.... I do not recommend these though because they do NOT perform the 2nd function... THIS is, however, the function that a 50 amp unit does better.
A true Power Guardian type Surge Guard. Monitors voltage (HIGH/LOW) and possibly Frequency and sometimes waveform.... These are the ones I recommend.. They also perform the first function (Spike Suppression) as well. They monitor for things like open neutral/ground/reversed polarity and such along the way.
They are also more expensive.
But even this fucntion is done better by the bigger unit (Bigger contacts on the relays)
