60 Amp Services

Most standard sized homes , Advice On Asbestos Disposal built prior to the 1960's were equipped with a 60 amp electrical service. This size of service was reasonably well suited to the needs of living at the time. However, the search for convenience and enhanced lifestyle has generally increased the demand on the electrical systems of homes , Pool Decking - The Perfect Way To Beautify The Area Around Your Pool today.

A common misunderstanding is that the ampacity (size, or capacity) of a home's electrical service is determined by checking the main breaker or fuses or the rating imprinted on the panel. This method of determining size is fraught with problems as the ratings of breakers, fuses and panels may correlate to the size of the electrical service, but in many cases they don't. The panel could have been upgraded without upgrading the service wires.

Electric Service Entry

The size of an electrical service is established by the ampacity (capacity) of the incoming service wires. The only reliable method of determining the size of the service is to observe and correctly identify the size of the incoming wires and the related equipment (mast, meter base, etc.).

It is becoming a common belief that electrical services less than 100 amps are inadequate, therefore unsafe and therefore, they must be upgraded. Smaller electrical services, such as 60 amps a not necessarily unsafe and are not categorically inadequate. A 60 amp service will however, limit the number of appliances that can be used at any one time.

For safey and practical purposes the adequacy of an electrical service should be judged against the size of the potential or expected load it will be required to carry. To some degree the load is determined by the size and number of circuits in the home , Pool Decking - The Perfect Way To Beautify The Area Around Your Pool and by the size of the home. , What is Energy Star Lighting?

One indication of a service that is undersized for the demands applied to it is the blowing or popping of the main fuses or breaker switch. If the main fuses or breaker is affected, the service is probably undersized. If the service is undersized for the current demands, increasing the size of the service is one option; an alternative is to reduce the quantity of heavy loads such as the oven, clothes dryer , An In-Depth Review of Popular Air Purifiers or water , Buy Window Coverings with Confidence heater. Central air-conditioners also draw heavy current and the installation of one may require the upgrading of the electrical service.

Another common belief is that if an individual circuit breaker pops or a fuse blows on a regular basis, the service requires upgrading. Problems with individual circuit breakers or fuses indicate only that the circuit involved has a problem and most likely, it is more heavily loaded than it was designed to be. A service upgrade would not necessarily solve this problem. What is probably needed is to reduce the load on the affected circuit, possibly by introducing another circuit into the area where it's needed.

"Knob & Tube" Wiring

Knob & tube wiring is a type of wiring which was in common use until the 1940's and sometimes used as late as the 1950's. The nick-name is derived from the ceramic knobs that are employed to insulate and secure the wiring runs and the ceramic tubes employed to protect the wires where they pass thru potentially abrasive materials (primarily wood , Installing Bathroom Flooring joists, studs etc.) Unlike subsequent wiring systems where all the wires in a run are enclosed in a cable, the two wires (black/hot and white/neutral) run separately and only come together at a terminal (switch, receptacle, fixture, junction box etc.).

Knob & Tube Wiring

Aside from the preceding concerns, the primary risk with knob & tube wiring, it seems, is it's relative accessibility for amateur repairs, , Pool Decking - The Perfect Way To Beautify The Area Around Your Pool upgrades and maintenance. It is not uncommon to see a system with knob & tube wiring that has a history of amateur work (poorly joined connections, unfastened runs, unprotected wires, etc.).
