After considering the application work, determine the carrier on which the breaker will be installed. Gorilla Hammers has assigned a 'Recommended Carrier Weight' range to each breaker. If the operating weight of the carrier falls within this range, the carrier will safely handle this model of breaker. If the desired breaker falls outside of this recommended carrier weight range, the carriers lifting capacity and oil flow will need to be verified to ensure a proper fit. Lifting Capacity: Provided the weight of the breaker does not exceed the maximum lifting capacity at any position, the carrier is assumed to be stable. On most loader backhoes and excavators, the maximum lifting capacity is lowest when the boom is at full reach. This is the value that must be compared to the operating weight of the breaker. Oil Flow and Operating Pressure: A required oil flow range is specified for each breaker. Oil flow to the breaker within this range is adequate for operation. However, for maximum productivity the carrier should be capable of providing the maximum required flow. Compare the maximum oil flow requirement of the breaker with the oil flow capacity of the carrier. Remember the breaker operates at 1500-2500-psi. therefore, oil flow should be evaluated at operating pressure.

Look at your breakers... take photo... look at brand name on breaker box.
Go to local store and see if they have same-similar breakers.

Is it acceptable to have 3 twin pull breakers in this box


If it was done by a licensed electrician it would be within code. The dependency is the load and the box rating. Obviously the current rating of the breaker is a concern as well as what is on it. If you have a low wattage circuit like on bedroom etc and split that with another one, it would be fine. But you should not put something like kitchen outlets on a split circuit.

I need a 2 pole half size arc fault breaker


If you are pressed for space in your panel, it would be easier to free up space in the panel by replacing some of your standard breakers with half size--or "piggy back"--breakers. The freed up space will permit you to install a standard arc fault breaker.

How do i know when 220 circuit breakers are bad


Always match breaker and wire size:
http://waterheatertimer.org/Color-codewire.html
http://waterheatertimer.org/How-to-replace-circuit-breaker.html

Feel if breaker is getting warm.
Listen for crackling sound.
Breaker is tripping.
Move wires to another same-size circuit breaker and see if problem continues.

Check watt or amp load on breaker.
For example water heater label shows 4500 watt non-simultaneous.
4500 watts divided by 240 volts = 18.75 amps.
You might think 20 amp breaker was good in this case.
However electricians use 80% safe maximum.
20 amp breaker x 80% safe max = 16 amps.
Water heater is 18.75 amps, so install 30 amp breaker.
30 amp breaker uses 10 gauge wire.
This means wire to breaker will run cool and not get hot, so breaker lasts longer, and there is more efficiency.
Using 80% safe maximum rule protects home, reduces heat wear on breakers and breaker box so everything lasts longer.

Ok, I have a half size GE 30 amp tandem breaker I want to install in place of a full size breaker to make room in my box. If I move it down one opening it will fit in, but not in the origional place of the...


Yes, but you should put in another half size breaker even if you don't use it so that you don't leave a hole in the front panel, unless you can find a half-size cover instead. I am puzzled about why the half-size breaker won't fit in the original spot. Maybe you are replacing a pair of full-size breakers that are linked together to provide 220V? If that is the case DO NOT replace these with half size breakers. Good luck.

My new home has a Siemens electrical panel with Arc Fault Breakers throughout the home. I consistantly experiance breakers tripping from all of these breakers, sometimes when the house has no one in it....


First let me state that I am not a licienced electrician,however I have done all sorts of construction work now for almost forty years.I have never heard of this being normal for properly sized and installed afci breakers.
I would contact siemens directly and see what they have to say. As I said this does not sound right to me.I think I would check with other electricians and see what they say. Thank you.

100 amp federal pacific stab-lok panel. It has a 70 amp main breaker, can I up-grade to 100amp? 41 year old home, copper wire, many empty slots in panel


I would recommend replacing the panel. You will pay just as much for one breaker as you would for a new panel. Please up grade ....Federal Pacific is not a safe panel to have. Breakers are know for not tripping. Please research to gain knowledge on FP...Jim

How to setup a thqp250 in a box?


These breakers are 1/2 size and only fit in an area of a panel designed for these. The bus bars must have extra tabs for these breakers. Before 2008 you could only have 42 breakers in a panel, so only some of the slots were reserved for these. Secondly, since this is a two pole 220breaker it must be in two spaces. This leaves a 1/2 space above and below the breaker. You could add a single pole breaker above and below. Now compare these in size, is there any way they can be as good as a full size breaker?

Why anyone would use a twin 2pole 30am breaker I'll never understand.
There is no way this size breaker could match up in quality to two full size 2-pole 30 amp breakers. If one wants to double up, do it with the 15-20 amp sizes.

Breakers Question


This is the most critical factor in choosing the breaker size. SMALL HYDRAULIC BREAKERS (HAMMERS): up to 1200-ft.lbs. (1627 Joules), are typically used in concrete and other light duty work. MEDIUM HYDRAULIC BREAKERS (HAMMERS): 1200 - 4000-ft.lbs. (1627 - 5423 Joules) are used in both concrete and rock applications with limitations on the size and amount of material to be broken. LARGE HYDRAULIC BREAKERS (HAMMERS): over 4000 ft. lbs. (5423 Joules), are typically used in rock and large scale concrete demolition projects.
