As always, if you are in doubt about what to do, the best advice anyone should give you is to call a licensed electrician to advise what work is needed.

Before you do any work yourself,

on electrical circuits, equipment or appliances,

always use a test meter to ensure the circuit is, in fact, de-energized.

Can you plug 2 full size fridges into one wall socket or into a power bar for safety?

No, full size refrigerators require a dedicated minimum 15 or 20 amp outlet.


Can you plug a 115v air conditioner into a normal household outlet?

The voltage is OK, but the current the A/C draws will govern the size of the circuit wiring and receptacle configuration. If the A/C unit is under 15 amps, a regular 15 amp receptacle can be used. If over 15 amps then a bigger size wiring will be needed depending on the amperage draw of the unit.


Can you plug a 120V amplifier into a regular socket in a household?

No, you can not plug a 240 volt amplifier into a 120 volt outlet. That said there are a number of step-up transformers available that will convert 110V to 220V - that's the simplest way to do it. You should make sure the transformer is rated at many times the power of your amplifier, because of inefficiencies in the amplifier. Look on your amplifier to see how many amps it uses at 220V. Double that number for going to 110 and add 20% more amps as a conversion margin. Take that number and multiply it by 110 to get the watts you need to supply. Size the transformer accordingly. eg. 5 amps @ 220V 5 amps * 2 = 10 amps 10*20% = 2 amps Total amps = 12 amps 12 amps*110 = 1320 watts In this example a transformer rated at or above the calculated wattage is recommended.


Can you connect an on-line UPS rated 1kVA with only a 15A power cable plug into a wall socket of 5A if you are not likely to load the UPS more than 5A at any time?

I suppose, but I never heard of a wall socket with 5 amps. The amperage rating of anything is based on the lesser of either the wire size or the circuit breaker. Minimum wire size for residential wiring has been #14 or 15 amps for years and years. If in fact it is really a 5 amp wall socket, then your question is moot. If we could all be sure that we could all the time control what is plugged into a wall outlet, we wouldn't need electrical codes, but someday you are going to move and whatever wiring you have will still be there, waiting for the next guy to plug in a toaster oven. Consider yourself forewarned. Lawyers love stuff like this.


What size fuse does a model 28 75114 craftsman use?

The fuse rating it 15 Amps and the size is 3AG..can be accessed by unscrewing the tip of the plug in connector.
