  4 Questions
Q: Can the cover be locked? I've looked for pictures on line but am unable to find any with sufficient detail of the latch. I'd like to use a small lock (think luggage lock) on the latch in order to keep curious children...or adults for that matter, from being able to open it.

Thank you,
Tracy

by Tracy from California on June 27, 2016

A: Yes, this will come with a latch for a padlock. Unfortunately, the picture does not show it very clearly.

If you have any other questions please let us know.

Thank you

Q: I have an outdoor main panel. Panel has one cirut breaker that goes to my home. Can I use this switch to power that breaker? I have 30 AMP generator (Generac GP5500.
by John from Indiana on February 08, 2013

A: The model CSR302 is designed to power one appliance/circuit and not used as a main to feed an entire panel.

You will need to find out what your mainline breaker size is to determine the correct size transfer switch needed.

The most common incoming amperage size is 200A and the most popular 200A outdoor manual transfer switch is model TWB2005DR.

Model TWB2005DR

It is best to consult with a certified electrician to confirm the correct switch for your application.

Q: Will this work for connecting to 30 amp dryer circuit, backfed to 100 amp panel? I have a 7500 watt generator for emergency power outage and only use about once a year.
by Ron from North Dakota on September 23, 2012

A: This switch is "Not" designed to back feed into your electrical service. It is extremely dangerous to back feed into your homes electrical panel even if you cut off the main breaker. You could easily kill a line worker.

This switch is designed to be connected to one circuit breaker.

To properly connect to your electrical service you should go through a 30A manual transfer switch with properly disconnects you from your electrical service.

30A Manual Transfer Switches

by Jared, Product Expert
Q: Will this work for a residence? I am only looking to put the transfer switch inline between the meter and the main panel. Would like the ability to switch to a generator feed during power outages (turning off most breakers and only using essentials. I have a 7500 watt generator with 2 30amp plugs
Thanks

by Gary from Colorado on February 08, 2011

A: This specific transfer switch is not designed or large enough to be mounted between the meter and your existing main breaker. You would need to look at the manual transfer panels we offer which is based on the amperage size of your incoming feed from the utility company. (100A or 200A)

Reliance 30-amp Outdoor Transfer Switch
High quality items at a reasonable price. Easy to install, my electrician was very impressed when he installed it. It was the perfect switch for my application which was hooking a generator to my well pump.

It Is What It Is. It Does What It Is Supposed To.
I ordered it, hooked it up and it works. It isn't the second coming, but it will likely keep you from meeting him for a few more years....

Adding transfer switch to allow well pump use during power outage. Quality of switch is very good and hook up was easy. Purchase from Electric Generators Direct was very smooth and without issues. Would recommend them as a seller.

Searching For A 230 V Quick Transfer Switch
The reliance 30 Amp product is a high quality solution made to last for decades.The product is PreWired -easy to mount and install. While my application backs up a 240 V circuit ,it can be easily modified for another application.
Pros: High Quality, Durable, Easy To Use, Price
Cons: Difficult To Punch Out The 34 Knockout

Great Product
Ordering was easy. The site said this box was back ordered but it shipped to me in about a week. Very happy to have it. I used it to power up a well. There was only one thing I would suggest you check. I pulled the plug out of the box and checked the wires. One wire was loose and fell off the plug. I tightened the wire back on and double checked all connections. It works fine and I have no regrets.

Customer Happy
I had a very easy installation with the transfer switch. The only change that I may suggest is the switch could use a positive off position. The ease of toggling from line to generator was too easy. In my opinion I would like to see a positive stop at the off position before pushing the switch into the generator position.

Other that that I could have given you a five star rating for equipment. The ease of ordering, the speed of delivery and the correct item too is great. The Quality of the... more
Pros: Durable, Easy To Use, Price, High Quality
Cons: If I Could Suggest A Slight Change
