Sparkys Out There?? (Electricians) Low Voltage Recessed Down Lights.?
Iv fitted 2 low voltage recessed down light in my bathroom just wanting to know what they mean in the fitting instruction.
in simple terms/
the cable used on low voltage electronic conductor must be greater in daimeter than the cable of the 230v mains??
help me on this 1 please all iv done is connected it to the old light cables is this ok??
thanks
thanks for the tips it all works ok.
the transformer has blue/brown cable mains also the 2 prong connectors both brown for the lights i think you can put about 6 light off 1 transformer
cheers for help

Please confirm the wattage of each lamp, total number of lamps/fittings and the v/a output of the transformer, before I can advise. It seems that you have a 105 v/a transformer, since you say it will take 5 lamps, but you only have two. This suggests that they are 20 watt lamps!! Sorry to say there will no be much light in your bathroom. I would normally install a minimum of 3 or 4 up to 8 x 50 watt fittings in a bathroom, depending on size. Please note that they should also be IPX5 rated if installed in ...(Answered by jayktee96) |

How can I find a break in an buried electrical wire without digging it all up?
I have 100 meters (100 yards) of 3 conductor (White, Black, Ground) wire buried to provide power for a well pump. The wire is buried without a conduit. The power stopped one day. I think that there is a break in the wire underground. I'd like to find the break, dig it up, repair it, re-bury it. Any ideas on how this can be accomplished without digginging up the whole wire.

The problem is probably either close to where the wire enters the house foundation or where it connects at the well head. Make sure your testing correctly.
If the house was built within the last 5 years, the back fill around the foundation has settled and put a lot of strain on the wire as well as the water pipe coming from the well. I would dig down 4 feet at the outside wall where the wire enters the foundation wall. However it's hard to believe that 12/2 Romex type wire would suffer enough tension force to break. Usually it's the ...(Answered by bobweb) |

What AMP current readings?
What is the general rule ratio of current measurement between hot conductor & neutral on a 120VAC circuit. When is it equal?

The rule is: What Goes Out Must Come Back.
Electrical energy is always trying to return to its source. In an AC Circuit, the current that is measured at the breaker (hot conductor) should be the same as the current measured measured on the neutral wire of the same circuit. The ratio is 1:1.
A GFCI (Ground Fault Circuit Interrupter) works on this principal. It measures the current on the hot conductor and compares that with the current returning on the neutral conductor. If the difference in currents is more than a few milli-amps the GFI trips....(Answered by JackSprat) |

Neutral & Grounding?
Why would you have neutral for 120VAC and not for 208/240VAC. ALso, if you measure current on a 120VAC conductor, what would neutral measure, since ground & neutral are bonded at the panel.
What case would you measure current on neutral. I have a situation measuring 10 volts A.C between neutral & ground, WHY?

A neutral is an electrical mid-point of a transformer winding. The power that comes to your house has three wires from the transformer. Two of the wires have 240 volts measured between them and are generally referred to as the hot conductors.
The third wire is the neutral conductor. Since it is connected electrically half way between the 240 volt hot wires it will measure 120 volts to either hot conductor.
The neutral conductor is bonded to earth through the ground conductor. This done for two reasons. One is to provide a solid, common reference point for the electrical system. The ...(Answered by JackSprat) |

Grounding a 200 Amp electrical service?
I ran a 4awg copper conductor in 1/2" EMT to the water main for a 200 amp residential service. The house is now finished and now the inspector says it needs to be in 3/4" emt, I can't find any code that says it has to be 3/4" emt. Can anyone here help me?

Simply put, the inspector has the final say. My suggestion is just switch it out. Bigger won't hurt and its less trouble than getting an inspector pissed off at you for a simple fix. Inspectors can make you life miserable so it is best to work with them not against them. Some inspectors set standard higher than the books require because they see the problems that can arise daily, they are there to look out for your safety and will make decisions based on their experience. As far as the water line grounding it is ...(Answered by digital tech) |
