Positive load side circuit breaker hook rails and uses HS-type hubs. Our Siemens GFCI hot tub breakers are UL listed on 60-degree and 70-degree Celcius conductors. This single-phase product has a one-piece bus bar construction specially designed for circuit breakers. Two additional spaces in the metal enclosure are included for branch circuits, and the interior protective panel removes in seconds. This is the replacement GFCI 50amp 230volt breaker for the optional Watkins 50amp GFCI sub-panel made by General Electric. This is very important for cold weather installations as nuisance tripping could cause the hot tub to freeze if undetected for days. Siemens premium GFCIs include Filtratec Technology to reduce nuisance tripping while meeting or exceeding the safety requirements for most hot tub installations and applications. Or perhaps by saying that all the current that goes to a load through the GFCI must return through the GFCI.The Siemens 50 amp GFCI hot tub breaker with a metal enclosure is designed for outdoor installations. The correct description of the functioning of a gfci is that it will trip if the algebraic sum of the currents through it is different from 0 by a threshold amount or, in non mathematical terms, if all the current flowing from source to load (on any wire(s) through the doughnut) is not nearly equal to the current returning from the load to the source over any one or combination of the other wires passing through the doughnut. Eaton BR GFCI circuit breaker, Ground fault personnel protection circuit breakers, 50 A, 10 kAIC, Two-pole, 120/240 V, GFTCB, Common, 14-4 AWG. If any hot leg current from source to load returns though a path other than the other hot leg wire OR the neutral then the return current does not cancel the forward current through the doughnut and the coil senses this tripping the mechanism. The neutral wire carries no current in this case. If all the return current (from right to left load back to source) is on the black wire the algebraic sum of the currents is +10 + (-10) = 0 and the device doesn't trip. from the source to the load on the red wire. Thus in the heater example say 10 amps flows from left to right i.e. Current flowing from left to right is positive and current flowing from right to left is negative. The doughnut has a coil wound around it and this coil detects the sum of the currents flowing in the three wires. Finally, all boxes need cover plates (15) to be safe (50 cents. Picture the wires (Red, Black, White) as running from left to right with the plane of the doughnut perpendicular to the paper (screen) and the load on the right. GFCI breaker, installed in the panel to protect an entire circuit, or with a. In a GFCI three wires pass through a doughnut. The missing element in your explanation is that current has a sign attached to it. In the case of a 220V heater connected between the phases the current on the neutral is 0 which is much less than the current on the hot. Thanks for any (and all) help/suggestions!Ĭlick to expand.Not quite. I will include pictures of my gfi wiring (which I believe is correct.and not the problem) as well as pictures of my panel and pj's print. So basically I need to understand why the GFI breaker is tripping and normal breaker is not. I plug in my panel to the breaker and it instantly trips the breaker.Īs part of my troubleshooting process to eliminate possible failure mechanisms I:ġ) Returned Siemens 50A GFI breaker and purchased another one (thinking it may be faulty) = same result (trips immediately)Ģ) Took out the GFI breaker and put in a 100A breaker I had to see if the wiring in my panel was bad.PANEL WORKS PERFECTLY I completed all the wiring, flipped the breaker on, tested for power at the plug.everything checked out. I put in a 50amp GFCI breaker at the main panel that is wired to a 4 prong plug on the other side of my basement. I am wiring up my control panel (used PJ's print). I will try to be as short as possible but here is my situation.
