Best transfer switch for generator Overview
Power surges, outages, and rations are incessant interruptions to reliable power delivery. Finding a good generator to ameliorate the power issues is only half the job. You need a transfer switch to enhance the seamless load switch in emergency and normal situations.
There are numerous factors to consider for selecting the best transfer switch for generators. We run you through the essentials that help you make a better decision.
Before going transfer switch shopping, the initial step is to understand your electrical needs. Whether a home or a business, have an electrical engineer compute the total load.
If you have a generator above 5000 watts, you need a transfer switch not only to ensure an uninterruptible power supply but to guarantee safety. Portable generators almost always need transfer switches compared to standby generators.
At the minimum, you need transfer switches as a legal requirement.
There are two types of switches, manual and automatic. A home or business owner has to flip the lever in a manual switch, but the automatic switch transfers full generator power when there is a drop in the power line’s voltage.
Depending on the type you choose, there are functional features you also need to consider.
What to look for when buying the best transfer switch for generators
Check whether the transfer switch you purchase has the whole installation device set. Power cords, connecting wires, and inbuilt or auxiliary junction box. Liaise with your electrician to determine what you need before purchasing. Most manufacturers include everything in the transfer switch, but it doesn’t hurt to counter-check.
Always purchase a transfer switch that can accommodate slightly higher wattage than your generators. Typically the best transfer switches for generators support up to 8000 watts.
Ø UL/CUL Certifications
Double-check to ensure the certifications are up to date. You do not want power surges causing flare-ups in your building.
The best transfer switch for generators must have a warranty. Reputable transfer switch companies have up to 5-year warranties.
Ø Type of switch
You have two options, manual and automatic. We’ll go ahead and say the manual switch is the best. It is inexpensive and imparts the same functionality save for automatic switching. However, if you have a higher budget, you can opt for the automatic switch.
If you live in an area with frequent power outages, you most definitely need an automatic switch.
