I am considering purchasing a Powerhouse 8,000 watt (10,000 watt surge) natural gas portable generator and have a 200 amp breaker box. Generator has 50 amp outlet. I live in a condo with all electric hvac, water heater, etc but natural gas is installed. What transfer switch do you recommend? Thank for your help.
Tom

Answer
Thank you for your inquiry!

The Reliance Controls Q510C would be a good option for your application so long as the transfer switch meets your circuit requirements. This transfer switch is fitted with the following breakers;
6x 15A 1-pole
1x 20A 2-pole
1x 30A 2-pole

You may configure this transfer switch so that it can support up to 4x 20 amp 2-pole and 1x 30 amp 2-pole breakers.

For the complete setup, which includes the switch, cord and inlet box, consider one of the Power Transfer Systems.

My current breaker box has three double pull 20 amp breakers for baseboard heating. I want to put a transfer switch in place that will accommodate three 20 amp double pull breakers. Will the reliance Q510C allow me to have more than the two double pulls the picture shows? I would want to have three 20 amp double pulls and two single 15amps. If this transfer switch won't do it, can you recommend one that would?

Answer
Thanks for your inquiry!

While the Reliance Controls, Q510C, would work for this application, It will require a small about of modifying to accomplish. This particular transfer switch is capable of supporting up to 4x 20 amp, 2-pole breakers and 1x 30 amp 2-pole at one time. Your specified configuration would be ideal with this transfer switch.

Although, if you are looking for a transfer system that you can configure at your leisure, then consider the Reliance Controls, TRC1005C, which is rated for up to 50 amps of generator power. This switch will serve as a 100 amp sub-panel, supporting whichever breakers you choose to install within.

I have a double pole 40amp breaker for my AC system. Would I be able to install a 40amp breaker on the transfer switch for this? Thanks
Lenny

Answer
Thank you for your interest in electric Generators Direct!

The manual transfer switches are tested and certified by the Underwriters Laboratory for use in their current state. Some manufacterers design these to accept limited modifications in order to accommodate different breaker configurations. The Reliance Controls, Q510c is designed to handle up to 4x 20 amp 2-pole breakers and 1x 30 amp 2-pole at one time. Unfortunately, a 40 amp breaker could not be supported within the switch as this is only compatible with breakers up to 30 amps.

We also do not recommend the use of a portable generator in order to power a central AC system. The systems in nature require a considerable amount of power and will likely not operate in their normal manner should they be put into this type of scenario.

Does the Reliance Q510C transfer switch which you sell for $379.00 come equipped with a full complement of circuit breakers? If the answer is YES, what brand or make of breakers are they?
George Lewchuk 
from New Jersey 
July 17, 2013
Answer
Yes, the Reliance Controls Q510C does come with circuit breakers.

They are currently using Eaton breakers but at any time they can change manufacturer based on availability. They are standard breakers used in these switches.

1 - 30A 240V
1 - 20A 240V
6 - 15A 120V

This switch does have interchangeable breakers so, you can alter the configuration to meet your specific application needs.

Note: Max 1 - 30A 240V breaker allowed.

Jim, I have a portable generator, 10000 starting watts, 8000 running watts. I'll be connecting to a 200 amp service. Do you think this transfer switch will work out for me?
Klink 
from Pennsylvania 
July 28, 2012
Answer
The transfer switch size should be based on the largest outlet size on your generator and a typical 8000 watt generator will have a 30A outlet on it. So, you would want to go with a 30A transfer switch.

All 30A connections, outlets, inlet boxes, cords and transfer switches have a maximum wattage rating of 7500 watts and the generator you have most likely has a 30A outlet available as the biggest outlet so the max you can run through that specific outlet is 7500 watts.

Any 30A transfer switch is what is required for this type of connection.

Jim, I have a 7500 watt generator that I wish to connect via a manual transfer switch. One of the branch circuits I need to connect is a 30Amp for a grinder pump. My intention is not to have this grinder pump circuit energized all the time,but will selectively energize it when using the generator. The grinder pump has a holding tank and doesn't run all that often. Problem is I can't find a 30Amp manual transfer switch with 30 amp breakers. Do you think the 50 amp 10 circuit reliance is the answer. would prefer to have a transfer switch as opposed to as switched sub-panel. Thanks

Answer
Since you have a 7500 watt generator there is no need to upgrade to a 50A switch. Reliance has a 30A which includes a 30A breaker....model Q310C, click on link for details.

I have a 150 amp panel and want to connect a 7500 watt portable generator. My electrician says that I would need a 150 amp transfer switch so that it doesn't burn out when it is connected to the main utility power. Would this 50 amp switch be sufficient or do I need the larger amperage?
Rob Ianuale 
from New Jersey 
January 04, 2012
Answer
Your electrician is misinformed and you need to match the manual transfer switch to the size of the generator outlet. Your 7500 watt generator most likely has a 30A 4-Prong twist lock type connection so using any 30A manual transfer switch will work.

Your electrician need to remember that when connecting to a manual transfer switch you are not trying to power the entire panel, only select circuits. Unless you want to power the entire panel then you would need to look at manual transfer panels instead of switches.

A manual transfer panel is typically mounted between your meter and main and would match the incoming utility amperage or larger if local code permits.

You may want to find an electrician who is familiar with installing manual transfer switches.

I have a 400 amp main panel, and a 200 amp sub panel, the sub-panel is in the garage and that is where I would like to have the transfer switch. Can the Q510 transfer switch be mounted and operated right next to a sub-panel, or does it need to be by the main panel? I figured that it would depend on what I wanted to have wired to it, but that if I needed to have a circuit from the main panel, the electrician would just need to run a longer wire to that location.

Answer
You can definitely wire the Q510C to the sub-panel. We do offer the installation guide on the website page for this unit. It is listed under the specs tab on the specific product page.

I recently purchased a generac XG8000E . Can I use a Reliance Q510C tran. switch hardwired to the 30 amp inlet box?
JIM 
from New York 
March 15, 2011
Answer
You can install a 50A manual transfer switch in this situation but you are still limited to the 30A outlet on the generator. The only reason to install a larger transfer switch would be if you are planning on upgrading your generator to a unit that has a 50A outlet.

I live in a mobile home with a 200 amp main. I own a generac 15kw 50 amp. Need to install a transfer switch to run whole house. What do you recommend?
John Gaskins 
from Louisiana 
February 26, 2011
Answer
This specific transfer switch is designed to power 10 circuits instead of a whole house. The following link is a model that would be more suited for this purpose and it is mounted between your meter and main which allows control of the entire circuit panel which would need to be managed so as to not overload the generator.

MODEL: TWB2005DR

Does the Q306C come as pictured with 6 breakers installed, or do I provide the breakers?
Bob 
from Maryland 
February 05, 2011
Answer
This product is supplied with a combination of 15- and 20-amp circuit breakers. In some cases, a 30 amp double-pole breaker may be supplied in the A and B positions.
All circuit breaker positions will accommodate 15- and 20-amp circuit breakers, and may be easily changed in the field.
