No, technically, the original Federal Pacific (FPE) breakers are no longer available. Stab-Lok® circuit breakers from the now-defunct Federal Pacific Electric Company (FPE) are no longer produced. However, the trademark and manufacture of the Stab-Lok® brand of breakers has been passed through a series of parent and subsidiary companies. Black and gray versions of the circuit breaker have been produced by these companies, with sales rights in the U.S. and Canada shifting back and forth.

Just as fluorescent lights are more efficient than incandescent lights, LED lights are more efficient to run than fluorescent lights. The specifics will vary from product to product, but LED lights are typically twice as efficient as equivalent fluorescent lights. A 13-watt CFL bulb can replace a 60-watt incandescent bulb, but a 6- to 8-watt LED bulb can offer the same amount of brightness. Fluorescent lights offer about 50 lumens per watt, while LEDs offer about 100 lumens per watt. LED light bulbs typically last two to three times as long as CFL bulbs, too. 

Yes, most electric and automatic gates can be opened manually. They are equipped with a manual override or release mechanism that detaches the motor from the gate, allowing it to be moved by hand. This feature is essential during power outages or other emergencies.

To activate the manual override, you will typically need a specific key or tool. In some cases, you may also need a screwdriver to remove a cover to access the release mechanism. The use of a key is a common security measure to prevent unauthorized individuals from manually opening the gate.

Because every model is different, it is highly recommended to consult your gate's user manual to familiarize yourself with the specific procedure before you need to use it. Keep any necessary keys or tools in an accessible location. Be aware that automatic gates can be very heavy, so opening and closing them manually may be difficult.

In North America, electric gates are also subject to the UL 325 Standard for Safety, which includes provisions to allow emergency responders to access the property.

Before the widespread use of PVC, affixing a ground wire to plumbing pipes was generally considered to be an acceptable workaround. Nowadays, not so much. There are plenty of nonmetallic water pipes and fittings out there, so any ground previously provided by the metallic piping would be interrupted in these cases, which is dangerous.
