I used a 6 by 6 by 6 metal box for this. The junction box out at the array. The grey PVC conduit goes to the house. The black cord comes from the first in the line of micro-inverters. The junction box is supported on MDO plywood, which is very water resistant — its what freeway signs are made of. I did this wiring before connecting the micro-inverter cables to the PV panels, and before connecting the new circuit breaker to the house power, so there was no power applied to this circuit during the wiring from either the PV end or the house power end. You will need one of these.

If that’s what you’ve got to work with, hey, that’s okay. Others may be adopting solar power because they have no choice maybe you live on an island, for instance, where there is no power. Regardless of the reason for getting or making your own solar panels, determine what they will be used for. If you want to provide power for an electric fence, you may only need one Watt solar panel so your investment will be quite low.
Connecting a Portable Generator to the Home Main Electric Panel – Part 1 June 18 By kevin 7 Comments With hurricanes coming ashore more often, I wanted a better solution than running multiple extensions cords to my portable generator whenever we experienced a power outage.
Off to the left, the grounding electrode conductor enters the box and terminates at the grounding bar. The feeder coming in the top of the disconnect has three wires, two ungrounded hot conductors, and a grounded neutral conductor. The two ungrounded hot conductors terminate at the disconnect, as they should. The grounded neutral conductor terminates at the grounding bar, as it should if this is where the service is grounded.
The feeder leaving the bottom of the panel has two ungrounded hot conductors, which terminate at the disconnect as expected. The grounding conductor terminates at the grounding bar, as it should. And the grounded neutral conductor terminates at the neutral bar. Unfortunately, since this appears to be where the service is grounded, the grounded neutral conductor from the lower feeder should be connected to the grounding bar. As it’s wired now, the grounded neutral from the lower feeder is connected to an isolated neutral bar.
Which means that the grounded neutral conductor feeding the panel is floating, or not electrically connected to ground. Without a reference to ground, the voltage potential between either of the ungrounded hot conductors and the neutral can be anywhere between 0 – volts.

If a single family home in the USA, you may be allowed to do your own electrical work , providing you apply for a permit from the local building authority. The inspector will answer any question you have but will not tell you how to to the work. If the panel has a main breaker in it, once it is relocated 20 feet, a main breaker will need to be installed at the meter location.
If you go this route you will definitely need to have a 20A breaker at the hookup panel to protect the outlet and anything connected to it. You wouldn’t need to have another 30A breaker for the RV outlet as the ganged breaker would be enough protection.
Always Disconnect the Power before beginning work! Failure to follow this rule can result in death or injury. Breaker and fuse panels remain hot even if the main breaker is turned off or the main fuse is removed. Main panels should only be worked on by qualified persons. Incorrectly performed electrical work can result in fire, damage to property, and injury or death to people. Furthermore, in some jurisdictions it may be against the law for anyone other than a licensed electrician to perform electrical work, and work which is performed by unqualified people or which has not been inspected and approved may cause your homeowners insurance policy to be void.
Why do some circuits have a neutral wire and others don’t? Because some appliances contain volt internal circuits such as timers and electronic displays which require a neutral connection to comply with current codes. When these 4 wire appliances are connected to old 3 wire systems via a 3 wire pigtail they use the ground conductor for the neutral.

Replacing a Breaker in Your Panel By Terry Peterman, the Internet Electrician Circuit Breakers A breaker is designed to protect your wires from carrying too much current, and to trip off on an overload or a short circuit. That is why proper sizing of breakers is so important i. Never oversize a breaker to solve a tripping breaker problem! The first question to ask yourself is — Why am I replacing this breaker? If you are adding a circuit, and now need to install the breaker, then this of course is necessary.

I would like to clarify further by adding some more detail to the scenarios I originally posted which may help the discussion. Install system grounding conductor in meter base by running properly sized copper wire from ground lug in meter base to ground rods or ground plate. From the meter base run 2 black and one white to combination panel with main disconnect. Neutral lug is bonded to ground bar in A combination panel. The system is properly grounded via the neutral wire between panel and meter base.
It is easier to get a wire to ground from outside a house or building than it is from the inside. You don’t actually need to run the system grounding conductor for the meter base as someone has mentioned as the neutral lug is bolted to the can which automatically bonds the meter can by supply side neutral which is grounded at the supply authority transformer. In house with copper water pipes install system grounding conductor in A combination panel by running properly sized copper wire to water pipe before water meter – street side and attach using an appropriate connector.
System is properly grounded. The meter base is also bonded to ground via the supply side neutral. I am most concerned about scenario 1 and if it is proper which I am told that it is.

Glossary Service Panel An electrical service panel is the main distribution center of your house’s electricity. It’s where the local utility’s service lines hook up with the individual circuits that run throughout the house. If you don’t feel comfortable working at the service panel, don’t take chances — hire a licensed electrician. In many areas, an electrician is also needed to hook up the service leads to the service panel and that’s also a good time to have the branch circuits hooked up.
Panel Components This section is not designed to help a beginner start work on a service panel. Remember, no one should attempt service panel work without having a firm understanding of what it’s all about. Here, we’ll explain the major parts of the service panel to give you a basic understanding of how it functions. Three utility service lines come into the panel.

Instead, I was looking for a flexible setup that was simple i. SOLUTION Generator interlock is nothing more than a sliding metal locking mechanism that allows a user to either turn on the main breaker or the generator backfeed circuit breaker. This method only allows either circuit breaker to be ON one at a time. You need to remember that when you turn off the main breaker, conductors a. Touching them directly conductors or indirectly lug nuts will result in serious injury or death so extreme caution is absolutely necessary.
So please be honest with yourself about your skills when working with electricity. When in doubt, please consult with an electrician instead. I placed my generator in a well ventilated area approximately 45 feet away from the house. You need to make sure that the generator is away from nearby windows, doors and ventilation intakes where exhaust gas could enter the house!
Remember, carbon monoxide is a silent killer because it is odorless and colorless. Being paranoid, I installed a carbon monoxide detector by the mudroom door nearest to the generator.
