"Repair Service to Fix Gas Boiler - WM Henderson first sends out a tech who is not familiar with gas boilers and admits there is an issue but does not know how to diagnose it. I had to pay $89 for this. Instead of having the right person come out, I had to to actively call again to get someone else to come out. The 2nd tech diagnosed the issue, but wants to charge me the same $89 that I already paid. - and quotes me $380 for the repair - and has to order the part. I agree and then call back the next day to confirm part is on order - and they tell me the charge is $1,015. I asked to speak to a manager to discuss, and no one is available and no one calls me back. I bought the replacement part from a supply where house (confirming it works with my make/model of boiler) and it cost me $165. I have had other scheduling issues with them as well. Don't use them!!!!!!!!"

Electrical questions, answered by experts

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.

You can determine what size generator you need for a transfer switch by matching the switch to the largest outlet on your generator. Larger generators can power up to 10 circuits, while most 5,000-watt generators can provide power to six circuits. So, if your generator’s largest outlet is 30 amps, you’ll need a 30-amp transfer switch.

This depends on how many outlets you have and the current status of your electrical system. The cost to ground an outlet clocks in at $75 to $480 per outlet, so multiply that by the number of outlets in your home to arrive at a rough estimate. However, this is for simple projects with no obvious issues with the system. Your final bill could vary widely from your calculations.

A voltmeter measures the voltage of AC or DC electrical current. Unlike a multimeter, measuring voltage is a voltmeter’s only function. Voltage is the potential difference between two points within a circuit. Measuring voltage with a voltmeter can help identify wiring issues or determine whether a battery is dead.

Your outlet should be a ground-fault circuit interrupter (GFCI). These outlets will cut power off in the case of an electrical fire, keeping your home and family safe. Extension cords can also be GFCIs. A local electrician can replace older outlets with GFCIs, if necessary.
