Is there a grounding system in the House?
The house is from the 1930’s and there wasn’t a grounding system. The contractors added a grounding system and installed GFCI outlets in the kitchen and bathrooms, but the rest of the receptacles in the house are still only two wire systems with no ground. What could cause the low voltage at the receptacles and why would the neutral side read hot?
What does 208v to ground mean on a transformer?
• On a 4-wire, delta-connected, 3-phase system, where the midpoint of one phase winding is grounded (high-leg system), the conductor with 208V to ground must be durably and permanently marked by an orange outer finish or other effective means [Sec. 110.15].
How big is a 12 volt wire guide?

Are there 12 volts on the same PIN?
Turn Ign on. (Not yet stated the engine) +12 Volts on the same pin. i.e. all the lefts or all the rights have +12 Volts between the pin you poked in and chasiss ground. Next you must. Put your MM into buzzer / continuty mode and check the other pins (The earth pins).
Can You ground both 12V and 24V alternators?
Leece-Neville makes alternators that are isolated GROUND. I have worked on several bus / Motorhome combo’s with 24 volt start systems and 12 volt house batterys. the ground was the same. the bus chassis had a 24 volt battery (2 12volts in series) for starting the 525hp engine and two alternators.
Can a 12v Negative lead be ground to the same ground?
Ground is ground. It should make no difference. Both *need* to go to ground! Ah but “can” they go to the same ground. I’d be inclined to say yes but, its a DC system so a 12V negative lead will have a different potential than a 24V negative lead. which might just cause a current flow that “could” be detrimental depending on several factors.
Can You ground 24v and 12V batteries?
Location: houston, Tx. yes, you can ground 12v and 24v to the same ground. the military vehicles we build at work have dual voltage setups. they use four 12v batteries and a battery wiring setup that is a bit different but it does work. i know it looks strange, but it works.
Can a ground side voltage drop cause electrical problems?
Ground-side voltage drop, a commonly overlooked cause of electrical trouble, can cause most of these symptoms. Any circuit or component is only as good as its ground. The more sophisticated electrical systems become, the more important their grounds are.
