Electrical Improvements

HaL Mandel All Messages By This Member #40609 开云体育 The revised electical laws regarding grounding of appliances and not using their chassis’ as a.c. returns hit home one day when I was cooking . ? I was stirring something on the electric stove with a stainless stirring spoon and reached for the ‘fridge door so I could retrieve an ingredient, and there was some sort of fault and I got knocked on my ass. ? The fault voltage, later measured was 65 volts from the chassis of the electric stove to the chassis of the refrigerator. ? I showed this all to my LL’s son and he took a chance on touching the pair of appliances at the same time, too. ? Sears was there the very next day with a new ‘fridge and a new stove. ?

Eric All Messages By This Member #40611 Bonding the stove frame to neutral, or to the grounding wire, serves to cause a circuit breaker to open if a fault within the stove tries to energize the frame? ? New (after the mid 1990s) stoves are set up, by default, for wiring to a new circuit that includes the two hot wires, a neutral and a grounding wire. ? If, however, the stove is connected to an older circuit without that grounding wire, a bonding jumper must be connected between the stove frame and the neutral.? Without that jumper, a fault within the stove can energize the frame without opening the circuit breaker....and the only way the fault is found is when someone gets shocked.? ? The stove works perfectly without that bonding jumper, so it is often overlooked/ignored...despite all the ever larger, ever brighter, ever more strident warning stickers.? ? ? Eric ? .

Bob All Messages By This Member #40613 I wonder if one of the appliances had an open neutral? I know the range was probably 240 v but maybe it still used 120 v for some functions? Any opinions?

HaL Mandel All Messages By This Member #40618 开云体育 There was a hood light and a hood fan. ? The oven didn’t have a light. ? The ‘fridge had a light. ? At the time I was very immersed in Mars Observer and was just glad the LL family treated me like family and had whomever manage the yanking and cranking while I spent my 16 hour days in Secaucus… ?

Jim VE7RF All Messages By This Member #40619 The 4 x burners on top of the electric stove all run on 120 vac....and still do.? ?One big and one small? burner each run on 120 vac....and are on 1 side of the buss.? ? ?The 2nd big and? 2nd small burner run on the other side of the buss.?
Bob All Messages By This Member #40621 Jim, A possibility I was thinking was if there's an open neutral?then the ground now becomes a current carrier. If the ground potential is different between the fridge?and the stove, current flows, a shock when touching both. What do you think?

Michael All Messages By This Member #40622 Yes, I remember this exact situation when I was growing up in the 50s. The solution my father had was to not touch the stove and refrigerator at the same time.?
Bob All Messages By This Member #40624 Well that would work!
