Reliance 31410CRK vs A510A Specs
Current Rating
Edge: Reliance Controls 50-Amp 10-Circuit Manual Transfer Switch
The Reliance Controls 31410CRK Pro/Tran is rated for 30 amps, while the A510A Pro/Tran2 handles 50 amps. This difference defines the maximum power load each unit can safely manage. A 50-amp rating allows you to connect larger generators or run more high-draw appliances simultaneously. The 30-amp model limits your total connected load to a lower threshold. If you plan to power heavy equipment like central air conditioning or large electric heaters, the higher amperage of the A510A provides greater headroom. For smaller setups, the 30-amp rating may suffice.
Wattage Support
Edge: Tie
The 31410CRK kit is designed specifically for generators up to 7,500 maximum running watts. This specification helps you match the transfer switch to your generator's output capacity. The A510A does not list a specific maximum wattage in its published data, though its 50-amp rating suggests it can handle higher loads than the 31410CRK. If you own a generator rated around 7,500 watts, the 31410CRK is a clear fit. For generators exceeding that output, you would likely need the higher-capacity A510A to avoid overloading the switch.
Included Components
Edge: Reliance Controls 30 Amp 10-Circuit Transfer Switch
The 31410CRK kit includes an 18-inch flexible conduit whip. This component attaches easily to the load center, simplifying the installation process by providing a ready-made connection path. The A510A description mentions an optional power inlet but does not list a conduit whip or other installation hardware in its included components. Having the whip included with the 31410CRK means you may save time and additional purchases during setup. The A510A may require you to source these parts separately.
Physical Dimensions
Edge: Tie
Both units share the same width of 4.5 inches, which helps them fit into similar spaces within your electrical panel area. However, their heights and lengths differ. The 31410CRK is taller at 13.8 inches and shorter in length at 7 inches. The A510A is shorter at 11 inches tall but longer at 11.8 inches. These dimensional differences affect how they mount in your load center. You should measure your available space to ensure one model fits better than the other.
Weight
Edge: Tie
The 31410CRK weighs 15 pounds, while the A510A weighs 17 pounds. The slight weight difference of 2 pounds is negligible for most installation tasks. Both units are constructed from rugged, powder-coated steel, which contributes to their durability and heft. The A510A is marginally heavier, possibly due to its higher amperage internal components. Neither weight poses a significant handling challenge for a qualified electrician during installation.
Circuit Configuration
Edge: Reliance Controls 30 Amp 10-Circuit Transfer Switch
Both models support 10 circuits, offering identical capacity for the number of home circuits you can protect. The 31410CRK specifies a maximum of 10 single-pole circuits and 5 double-pole circuits. The A510A does not provide this specific breakdown in its published data, only stating the total 10-circuit count. If you need to know exactly how many double-pole slots are available, the 31410CRK provides that clarity. Otherwise, the total circuit capacity is equal for both.
Which Reliance Transfer Switch Fits You
Users needing higher power capacity for large loads
Our pick: Reliance Controls 50-Amp 10-Circuit Manual Transfer Switch
The A510A Pro/Tran2 supports 50 amps, allowing you to connect larger generators with higher output. Its 50-amp rating handles more simultaneous circuits than the 30-amp model. If your generator exceeds 7,500 running watts, this unit provides the necessary current rating to keep essential appliances running safely during outages without overloading the switch.
Those wanting a complete installation kit with conduit
Our pick: Reliance Controls 30 Amp 10-Circuit Transfer Switch
The 31410CRK includes an 18-inch flexible conduit whip, simplifying the connection to your load center. It is designed specifically for generators up to 7,500 running watts. This included component saves you from purchasing separate wiring materials, making it a practical choice for standard residential installations where the 30-amp capacity meets your power needs.
Buyers prioritizing a compact footprint for tight spaces
Our pick: Reliance Controls 50-Amp 10-Circuit Manual Transfer Switch
The A510A measures 11.8 inches in length and 11 inches in height, making it slightly more compact in certain dimensions than the 31410CRK. While both handle 10 circuits, the A510A offers a 50-amp capacity in a package that may fit better in confined electrical panels. Its manual operation ensures reliable switching without complex setup.

Frequently asked questions
What is the main difference between the Reliance 31410CRK and A510A?
The primary difference is the amperage rating. The 31410CRK is a 30-amp unit, while the A510A is rated for 50 amps. This higher rating allows the A510A to handle larger power loads from bigger generators. Both models manage 10 circuits and operate manually.
Which transfer switch is better for a 7,500-watt generator?
The Reliance 31410CRK is ideal for generators up to 7,500 watts. Its 30-amp capacity matches the typical output of these mid-sized units. You get a durable steel cabinet and ten circuits for essential home loads without needing the extra capacity of the 50-amp model.
Does the A510A fit in the same space as the 31410CRK?
The dimensions differ slightly between the two units. The 31410CRK measures 13.8 inches in height and 7 inches in length. The A510A is shorter at 11 inches high but deeper at 11.8 inches long. Check your enclosure space to ensure the deeper model fits.
Can I use the 31410CRK for a whole-house backup system?
The 31410CRK is designed for ten circuits, covering essential home loads. It is best suited for users who do not require the higher 50-amp capacity. For whole-house systems with greater simultaneous power demands, the 50-amp A510A is the more appropriate choice.
Are both switches manual or automatic?
Both the 31410CRK and the A510A are manual transfer switches. You must physically turn the handle to switch power from the utility line to your generator. Neither unit offers automatic transfer capabilities, requiring you to be present to start the generator and engage the switch.
Which model is heavier?
The A510A is slightly heavier than the 31410CRK. The 31410CRK weighs 15 pounds, while the A510A weighs 17 pounds. This minor difference in weight comes from the internal components required to handle the higher 50-amp current rating safely.
Do both models have the same number of circuits?
Yes, both units support exactly 10 circuits. This allows you to power the same number of individual outlets or breakers in your home. The choice between them depends on the total amperage required, not the number of circuits you need to protect.
Is the A510A suitable for high-power manual backup systems?
The A510A is specifically designed for high-power manual backup systems. Its 50-amp rating allows it to handle larger generators and greater simultaneous loads. If your power demands exceed what a 30-amp unit can provide, this model offers the necessary capacity for larger homes.
