I will be running 30 amps through the relay won't 16 gauge wire burn under that load. My circuit is 10 gauge.

Keep the length of the 16AWG wires as short as possible and use the larger wire for the rest of the run it will work fine you don't have to change the 16AWG all the way to the socket. The resistance is dependent not only on the cross sectional dimension of the wire but the length of the run

If you are intending to run 30 amps continuously then I would agree the wiring may be a little small. You could remove the spade contacts from the connector, carefully open the crimps securing the wire to the contact and recrimp/solder your 10 gauge wires to it. The relay should be good for 30 amps.

Short answer is #10 for 30 amps. Bigger if you plan on going more than about 15 feet because of voltage drop.really great charts here for sizing wire for 12v dc circuits:http://www.zetatalk.com/energy/tengy10s.pdf

They were designed for 30 to 40 amps according to the manufacture. I think you are thinking like house wire that is AC. With DC if I remember correctly you can run 30amp through 16 gauge for approximately 5 feet. But longer distance require lower gauge. 10 gauge is.good for a run of 20 feet. But I agree thicker the wire the better.

I concur with the other 7 answers you've received so far. The only worry might be the extra 10 amps, 25% more than what the original installer decided on. My breaker hasn't blown but hasn't had a reason to do so.

don't know what you are trying to ask, the are great relays , 30 amp max load!!! not weather proof must be kept in a dry area away from water splash

Yes, you really should. It might not always run 30 amps continuously when it's on, but if you have anything else on it, you really risk tripping the breaker. (Obviously, 20A or lower breakers would not do at all.)

30 amp 220 volt breaker and 30 amp wiring only! Using a smaller breaker and wire is a fire hazard because breakers don't always trip when overloaded! If the 20 amp breaker fails to trip then the wire will heat up like a burner on an electric stove and will catch on fire.

I used 16 gage and my system sounds fine. The thicker the wire is, the better. But I think 16 gage is fine for most applications.

You can't use 10/3 wire with a 40 amp breaker. You can only use it with a 30 amp breaker. You would need to use 8/3 wire with a 40 amp breaker. (You can use bigger wire with a smaller breaker, but not a smaller breaker with bigger wire.)

I use a lot of 16 thru 12 ga. wire depending on current draw. Connectors are available very heavy current to the lighter stuff, i.e., 22 ga. Do a search and see. de K0xxx

It looks like no more than 18 gauge to me. The insulation on the wire is extra thick to make it seem like you are getting a 30 A capable wire. The thick insulation and thin actual wire make it easy to damage the wire when you strip it back. It'll handle 30A surges, but I wouldn't use it for 30A continuous.

This is a more complex problem than it would seem. I tend to use overkill when sizing wire to a given load. In addition, a friend replaced all of my fixtures original quartz halogen bulbs with LED's that draw less current. And generally speaking, it is not just the load in amperes, but the length of the wire run in feet that determines the wire gauge needed. I would suggest that you employ someone with knowledge in electronics to size and determine your layout. This is especially true if your layout is complex and heavily loaded. I wish I could be of more help, but I have to hire an electrician. Good luck!

10 amp. in a fuse link should be fine. If it pops after extended run time, bump it up to a 15 amp. Remember the fuse should be the weakest point in the circuit so any fuse should be OK if you use the right wiring and nothing gets warm.

I have SIX panels and I can't break 30 amps. The ratings are PERFECT, not reality. Line losses, connection losses, etc all drop the actual down. Just wire with the maximum thickness copper wiring you can.

simple rule of thumb at 1500 watts this unit draws 12 amps so needs a minimuim. 15 amp breaker. wire gauge is also amp rated a follows 14ga. = 15 amp, 12ga. =20 amp 10ga. = 30 amp. .....need more wire size to amperage handling check nec(national electrical code.)also note the longer the wire the heavier gauge it needs to be. example 10-25 ft. 14 ga is most likely ok 100 ft go to a 12 gauge. after a few minutes of running the unit on an extension take hold of the extension cord is it getting hot, if yes get a heavier cord.

Just got mine set up, used a 10 gauge wire (3 wire, solid copper) to a 30 amp breaker, works great. The motor is rated for 23 amps on the machine so 30 should be plenty of power, plus its only 230v.

No. this will not cause any problems. the unit does not pull enough power to overload 16 gauge.

yes, but you can't exceed 80% on whatever size wire and breaker you have. For example if you have 10 gauge wire and a 30 amp breaker you can puta total of 24 amps on a single circuit. Realisticly the max thermostoat or relay is 22 amps for 10 gauge.The max for 20amp 12 guauge is 16 amps of heaters which is a tad over 3800 watts.4000 watts would be slightly over the max for a 12 guage 20 amp circuit.

The breaker swap would be effective but you must also assess the wiring. It is likely that your 40 amp circuits are on too light a wire (I would bet they are #8 at best). Recommended in this install is #6.
