	Fault the system. If the relay is working properly, it will not re-close. From: What is an anti-pumping relay? \| Electrotechnik - The Website on ... The anti-pumping relay is a device in circuit-breaker whose function is to prevent multiple breaker closures. For instance, if the operator gives the closing command to the breaker by pressing the close button and the breaker closes. However, a fault in the system causes the breaker to trip. Since the closecommand is still in the pressed condition, there is a chance of the breaker closing again and being tripped by the relay multiple times. This can damage the closing mechanism of the breaker. The anti-pumping relay prevents this by ensuring that the breaker closes only once for one close command from the control panel.

	"I worry sometimes that we enable unqualified people to try and do dangerous things." Me too. But, I get yelled at if I say as much, even in my tactful, gentle way. My hope is that, even armed with our insightful, intelligent answers, they will still not posses the ability to build anything dangerous.
