Transformers rely upon electromagnetic induction, the process which occurs when the alternating current within a circuit generates current in a nearby circuit. Transformers vary in design and size, as well as using different amounts of current. Transformer outlets can be used to connect any appropriate device to a surge protector. All rights reserved.

Seven of those amounts to 14 amperes, not amperes. The transformer outlets are spaced farther apart than the other outlets to accommodate transformer block adapters or any Power strip for transformers adapters that are large in size.

For example, they are popular with American expatriates who don't want to throw away their American appliances when moving to Europe. Unfortunately, when used incorrectly, step-down transformers can be dangerous. This article is a cautionary tale of one incident that could have ended in disaster. What this means is that the volt output is not electrically isolated from the volt input.
Non-polarized "schuko" power plug Schematic of step-down transformer, opposite plug orientation The problem with surge protectors Usually, having volts between neutral and ground in an appliance designed for volts is not a problem — the insulation has a large safety margin.
However, if you connect a surge protector or a piece of equipment with built-in surge protection on the volt side, bad things can happen. Some surge protectors contain only a single varistor connected between hot and Power strip for transformers those will work fine with a step-down transformer. However, many surge protectors have additional varistors connected between hot and ground and between neutral and ground. When a surge protector of this kind is used with a step-down tranformer, one of these varistors can be subjected to the full volts.
This is Power strip for transformers to trigger the varistor into its conducting mode, effectively treating the volts as a surge. I had moved back to Europe from the U. Because the transformer had only one outlet and I needed to connect multiple appliances, I used a U. This worked fine for several weeks.
Then I went travelling and unuplugged everything just to be Vegas private entertainers. When I returned and plugged the step-down transformer back in, there was a bang and the lights went out.
A fuse had blown in my apartment's breaker panel. I replaced Adult bermuda fuse and tried plugging in the Power strip for transformers transformer again; the fuse instantly blew for a second time.

This is what must have happened: When I returned from my trip, I plugged in the surge protector the opposite way from before the trip. Schematic of connections at time of incident What could have happened It could have been much worse. This left the power strip with a short between hot and grounda very dangerous condition.
If at that point I had plugged the step-down transformer into an ungrounded outlet, the chassis of any grounded volt equipment connected to the power strip would have been live with voltsand I would have stood a good chance of being electrocuted. Never use a surge protector on the volt side of a to volt step-down transformer if the power plug can be plugged in two different ways. It could kill you. If you must use a power strip, make very sure it doesn't have surge Psychology of swinging built in.
If you are in a country with polarized power plugs, such as the UK, this problem is less likely to affect you, but it's still possible if either the wall outlet or the power plug of the transformer has been wired with incorrect polarity. Exercise care. A step-down transformer. Schematic of step-down transformer, one plug orientation.
